Choosing the Best Shower Chair for Your Loved Ones with Mobility Issue

May 13, 2022

For people who have lost their mobility due to old age, injuries, or illness, showering can be challenging and exhausting without the help of mobility aids like a shower chair.

They will not only have difficulty mustering the strength to accomplish the task at hand, but they are also prone to accidents that might aggravate their condition.

Shower chairs help people with reduced mobility conserve their energy, feel more comfortable and safer.

This article will try to educate and empower people in choosing the best mobility chairs for their loved ones.

Here’s what you need to know about the different types of shower chairs and the features to look for.

What is a Shower Chair?

Shower chairs are waterproof chairs known by various names, such as shower seats, commode chairs, and shower tools. They are designed to be seated by patients suffering from temporary or permanent mobility impairment while inside the bathroom.

Most chairs have rubberized, non-slip feet, padded backrest for support and comfort, and a reinforced heavy-duty frame.

Different Types of Shower Chairs

Although mobility chairs provide the same function, they come in different sizes, shapes, and mobility levels to cater a specific mobility need.

Here are some common types of mobility chairs to choose from.

• Standard Shower Chairs

Have four rubberized feet, a wide seat, a backrest, and armrests. It also provides more stability, space, and support to the user.

• Bariatric Shower Chairs

This chair is suitable for bariatric users and usually has a higher weight capacity of 300kg and a wider seat area to accommodate the occupants.

Other features include a padded backrest and armrests for extra comfort, a reinforced heavy-duty frame for improved safety, and aims to provide support when sitting or transferring.

• Fold-Down / Collapsible Portable

Designed with aluminum for longer usage and is easily collapsible for storage and convenience when traveling. It is ideal when other people are using the same shower and it needs to be removed in the bathroom and then put back.

Over Toilet Aid sample img For so many years, people with mobility issues like the seniors and patients receiving healthcare have been using different assistive devices to make toileting easy, safe, and hygienic.

But today, we are going to talk about toilet aids and how they can transform home health care and improve the quality of life of people with reduced mobility.

What is an Over Toilet Aid?

Designed to make the process of toileting safe and increase user independence, toilet aids are usually made from a non-corrosion and reinforced aluminum frame with adjustable legs and raised armrests to assist the user in transferring on and off the stool.

Also, most models of toilet aids have durable non-slip feet to provide a firm grip and stability in wet bathrooms or conditions.

Benefits of Over Toilet Aids

The use of this assistive device has proven to be very beneficial for people who could not use the toilet on their own without assistance.

Here are some of the benefits of toilet aids.

Offers Extra Layer of Security and Stability

The first is for safe toileting. We know that as people age, their strengths are no longer the same when they are young. Their legs become weaker and unsteady. Getting on and off the toilet safely and comfortably can be challenging. And the risk of falling is very high.

But with the help of toilet aids, toileting becomes safe and easy because of the stability and support that the device provides.

The adjustable and sturdy features of the device offer an extra layer of stability and security for people like the elderly who are prone to falls.

For bariatric users, the reinforced aluminum frame of most toilet aids can accommodate this type of patient.

Increase Toileting Independence and Privacy

Regardless of our age and health conditions, we all have the right to preserve our dignity in doing a personal task like toileting. These toilet aids not only promote toileting independence but also provide some privacy to people with mobility issues.

Some types or models of toilet aids have features that allow the users to clean themselves without the help of their caregivers.

Also, other models like the split seat over toilet aid have new seating that provides full access to all the body parts of the patient, and there’s no need to stand off the chair to have their body parts cleaned.

Improves Quality of Life

Toileting is a part of our daily life regardless of our age and physical conditions. But for people with limited mobility, this task can be a bit risky and challenging.

With the availability of these assistive healthcare devices, people with reduced mobility can once again have control of their life even just by doing this task. And eventually can help improve their quality of life.

Summary

With all the benefits and added features that toilet aids offer, getting on and off the toilet can be safer and less complicated for those who might need some assistance. Whatever be your circumstances and specific needs, there are a lot of toilet aids that can help you.

If you are a man with low testosterone in your system, it only means to say that your body is not making enough of it. According to TRT Australian doctors, this hormone is not just valuable for your sexual activity, but it also has a crucial role to play in your emotional and physical health.

men's exercises

There are diverse reasons why T-levels go down. Sometimes, it may have something to do with aging itself. Or it might be due to a physical trauma on the testicle or other health conditions could be behind it. If you are taking certain medications, there is also a good possibility that it could bring down your T-levels.

New studies reveal that low testosterone may be associated with obesity in men. Diabetes Care, a popular medical journal with a wide readership and following on the Web and social media, published an online article about this. According to them, men with type 2 diabetes and who were obese are likely to experience indicating symptoms of low-T conditions.

Besides, obesity and low testosterone are deeply intertwined with each other. As for the low-T condition, the scientific and medical communities know for a fact that it has something to do with the exacerbation of other medical conditions, such as heart ailments.

The indicating symptoms of low testosterone can be best managed by losing some weight first. Building some muscles in the male human body is also paramount to increasing T-levels. This means to say that the more muscle volume you have in your body, the more testosterone that your system will produce for this.

Why Exercise is Important Here?

Men who seriously want to turn around their testosterone level and alleviate low testosterone symptoms should consider exercising and make it part of their routine.

The Journal of Andrology published the outcome of particular research involving 32 men diagnosed with type 2 diabetes and low testosterone. The subjects of the study were given, for 52 weeks, a solid and supervised diet and exercises. This is in conjunction with relevant testosterone replacement therapy.

At the end of the 52-week study, these men underwent blood testing for testosterone and their results showed positive signs of improved concentration.

As can be gleaned from the results of the said study, it tells that physical exercise may significantly contribute to turning around testosterone levels in men. It can effectively reduce the amount of indicating symptoms for low-T.

There is an unequivocal truth on this, that physical exercise brings about manifold benefits to the male human body. Aside from weight loss and toning your body shape, working out can influence bone density and improve mood. These two aspects can suffer from the adverse effects of low testosterone.

Exercises for Men

While every single form of exercise has its own set of benefits to the male human body, medical experts are suggesting a specific approach to men’s workouts, particularly those with low-T symptoms. This is most beneficial to men whose low testosterone condition hindered them from working out in the past.

Here are some relevant recommendations to come by:

Keep yourself on doing some weights

These kinds of exercises allow for the biggest boost on testosterone levels. Weight and resistance training both can significantly help in building strong muscles. But they can also intensify cardiovascular activities such as walking or running.

Immerse Yourself into Cardio Workouts

The viable role of cardiovascular activities can’t be put aside here. They have a significant impact on cardiovascular health and weight loss, and they also tend to influence testosterone levels in men.

Aerobic exercises are beneficial if you are aiming for weight loss, however, you need to accompany them with strength training using resistance or weight machines. Such melding together of approach in physical workout lays the groundwork for reliable improvement of low-T symptoms.

Partner Up with a Professional Fitness Trainer

If it has been a long while since your last workout or you are new to the world of exercise, you don’t need to find yourself groping here but you can enlist the help of a personal trainer. He can help identify for you the best forms of exercise that will help address your low testosterone symptoms.

Wrapping Up!

If you have suspicions that you may be a running candidate for testosterone replacement therapy but are uncertain of what course of action to take we suggest that you consult a TRT Australian medical professional for this. They will have you undergo a blood test to measure up the testosterone in your bloodstream, after which they can provide you with a viable treatment.

What are the Positive Effects of Using Adjustable Beds?

| Health and Beauty, Home Improvement

hospital beds While the use of traditional beds is here to remain, we want to encourage you to invest in adjustable beds especially if you are seriously looking for practical ways to optimize your sleep space.

But before anything else, we need to establish what an adjustable bed is. An adjustable type of bed gives users the freedom to either raise or lower the top or the bottom part of their bed allowing them to identify the most relaxing position they can have during sleep. This way you don’t have to spend a good amount of 15 minutes or so arranging a pile of pillows. Here are some of the beautiful reasons why you should consider using this type of bed today.

1. Alleviates Lower Back Pain

Not many people are aware that an adjustable type of bed can significantly help in alleviating lower back pains. In case that your spine is not in the proper alignment or if one side of your body is creating too much pressure, you’d normally wake up to having chronic pains in the lumbar area.

To help alleviate this condition, some people would choose to sleep on their side and clutched between their legs are some pillows. Or you may choose a better way, and that is making the bed you sleep in to do the work for you.

By lifting part of your bed by at least 45 degrees, your lower back’s compression can be mitigated. Alternatively, when you raise the bottom part of the base, you will pull down the stress level on your spine’s middle section. Adjust the mattress height until the back pain dissipates.

2. Improves Breathing

Doctors would always tell people who are suffering from sleep apnea or with any other type of sleep breathing issues to always see to it that they sleep at night with their heads somehow a tad elevated. If you think that by stacking 4 pillows at a time and the rest of your body would remain flat, then know that this is likely to bring along its own problems – serious discomfort for you.

One of the primary reasons why adjustable beds are better in comparison to traditional beds is because they allow you to elevate the top of your body easily to a nice position where you can still have a good night’s sleep while keeping your airways open.

3. Increase Your Level of Independence

For the senile people, one of the major benefits they will enjoy from using an adjustable type of bed is that it allows them to get or move out of bed on their own. This also holds true for anyone who has recently suffered a serious physical injury at any age.

If you are one of the many people out there who are somehow struggling on getting themselves to a sitting position for them to get their feet on the floor – an adjustable type of bed will do wonders for you, big time.

Another trick with an adjustable bed is to make the top part of this bed up, this way you’d be able to swing both of your legs over the side. This sounds a whole lot easier, right? As opposed to trying to grab your hands on the nightstand while trying to roll over toward the ground.

Wrapping Up!

The advantages of us adjustable beds are far too many to count, however, the points given above are a good starting point for you to think of making the switch. If you are seriously looking for ways to improve the quality of your sleep and always wanted to experience how a restful night feels like, acquiring this type of bed should be topping your list. Before you know it, you are already enjoying a full 8 hours of restful sleep at night.

What Does a Hair Fibre Spray Do To Your Hair?

Can They Make Your Hair Grow?

When it comes to certain kinds of hair thinning and hair loss products, hair concealing fibres are topping the list because they are among the most promising in this line. While many of those who are suffering hair loss issues would consider hair transplant surgery as their final go-to treatment when everything else fails and they’re financially capable of the process, it is not always the right choice for all types of balding.

Like for example, at the outset of balding, there is still a good chance to stop hair loss or reverse it naturally. The same is also true when it comes to the diffuse type of hair thinning. Surgery may not be at all that necessary or practical unless there is observable progress of hair loss.

It is a great relief for individuals suffering from the pangs of balding to know that hair concealing fibers should be considered as a natural option, particularly by those who are afflicted by early-stage hair loss or diffuse thinning. Some users like to use hair fibre spray to keep the product hold firmly and stay in place after application, although most of the time it is not necessary most especially if you happen to be using a high-quality hair building fiber.

Hair-Building Fibers, What Are They?

Hair-building fibres are a qualified hair thinning treatment product. They come to significantly improve how your hair looks. You apply the product on your hair, but not on a completely bare or bald scalp, otherwise, they will have nothing to hold onto except to fall directly onto the scalp surface.

Right after you apply the product onto the affected or thinning areas of the scalp, it will instantly put on some volume to that area. As a result, you are going to have a seemingly fuller or denser hair.

Not only does this type of hair thinning concealing product give results in an instant, but they also help and contribute to promoting healthy hair. This is because they contain nourishing nutrients, which is good for scalp health.

Hair Loss Concealing Fibers, How do They Work?

Hair building fibres work by intertwining themselves with the individual strands of your hair. They will automatically attach to your hair strands because they are made from statically charged keratin proteins. This is the same building blocks from which human hair is made of. The naturally hair-entwining properties of such products will give you the appearance of denser hair in an instant – right after the correct application of the product.

When these protein fibre strands entwine with your hair, they will blend in on their own and after that they are likely to stay in place throughout the day until such time that you need to wash them off in the shower.

However, some users feel that they need to couple the use of the hair fibres with a hair fibre spray in the hope that it will give the product a more fixed setting, even though most of the time it is not necessary. Since they are statically charged, they will not easily fall off from your hair to your blouse or shirt.

Hair fibre products are hardly detectable, and that is the truth. They are highly effective in removing the appearance of bald spots or if you want to make your scalp less visible to everyone around, most especially from the prying eyes of people around you. The use of hair-building fibres is an instantaneous way of giving your hair the much-needed, well-deserved oomph.

What’s About Testosterone That Makes Men More Prone to the Coronavirus According to TRT Brisbane Doctors?

| Corona Virus Pandemic, Men's Health

If you will look at the recent number of deaths due to the COVID-19 pandemic, you will realize that it is having a bigger toll on men as opposed to women. This observation has stirred a lot of heated debate in the medical and scientific communities regarding what could be the possible underlying reason/s behind it.

One conjecture, plausible enough to be looked into by the experts has something to do with the male sex hormone, testosterone. Medical professionals, whose specialty is in this area, believe that the male sex hormone comes with an inherent dampening impact on the male immune system.

Those who support this supposition are convinced that testosterone makes men more susceptible to the novel coronavirus.

man in mask frontliner

“How can this be?”

This is the million-dollar question being asked by the vast majority of trt Brisbane doctors. According to scientific evidence, estrogen plays a key role in improving the female immune system and may also enhance immune inflammation. On the other hand, the male sex hormone, testosterone comes with a contrasting impact because it dampens immune response.

This explains the reason why women have less than severe infections when they contract a serious illness but the opposite of which is true to men. Besides, it significantly contributes to the stronger immune responses of women’s bodies to vaccinations (basically, these are less potent versions of the virus).

If a man happens to have a higher testosterone level, the odds are high that he may be suffering from weakened immunity. This usually manifests in having low antibody responses, particularly to annual vaccinations for flu.

This brings us to an assumption, general perception of many of us, that men have a natural susceptibility to suffering more intensely from bacterial infections, but more so when it comes to contracting a deadly virus much like the one that leads to COVID-19.

Are There Any Trade-Offs To This?

A significant portion of the research done concerning the supposed suppressing impact of the male sex hormone, testosterone, on a man’s immune system centered mostly on individual immune cell types or immune function. However, we need to keep in mind that the human immune system is as intricate as intricate can be. It is made up of many different types of cells, tissues, and organs, and together they create a complex response to a threat of possible infections. We can classify this response into 2 categories, adaptive immunity, and innate immunity.

The best way to describe innate immunity is that it takes place within hours, so it is rapid and also nonspecific which means to say that it is one of the human body’s frontline defenses. It is programmed to target all kinds of foreign invaders. In addition to that, it retards infections up until the time comes that adaptive immunity is fully developed.

As for the acquired or adaptive immunity, this is a bit more complex in such a way that it will require a much longer time to process and identify a foreign matter invading the body before it can start producing specific antibodies that will take charge of it.

Long after the threat has been eradicated, the body’s adaptive system of immunity “remembers” it fully. This causes the body to make a similar response to the same pathogen but way faster, power, and more efficiently.

According to TRT Brisbane doctors, adaptive immunity is energetically taxing on the human body. What does this mean to say? This signifies that men who happen to have high T-levels in their system, the energy-hog actions such as risk-taking behavior, sexual appetite, and increasing muscle strength, all these would not necessarily prioritize adaptive immunity.

So much so that when men become seriously ill or acquire an infection in their bodies, the natural tendency of their testosterone level is to take a plummeting action. One way to explain this is that by moving energy away from every single high-energy consuming task, that amount of energy can be diverted to strengthening immune response instead.

Overall, testosterone can suppress the immune system or it can have a strengthening effect on it. But there are also occasions that it will not be impacted in any way.

With regard to these varying results in different investigations, it only goes to show that if you will only gauge certain immune features with respect to testosterone itself may not provide us with any solid immune capabilities of the body of a man.

What Does TRT Australia Say About Exercises That Allegedly Increase Testosterone Level?

Is there a possible way that the people behind the TRT Australia industry affirm to us the veracity of belief of many of us that there are certain kinds of exercises that can help increase testosterone levels in the male human body? If there is any truth to this, then what are those workouts that can help in this regard?

A study carried out by a team of medical professionals from Harvard Medical School suggests that more than ⅓ of men past the age of 45 are likely to have reduced amounts of testosterone in their system. In line with this, a handful of women also tend to show symptoms of deficiency in this area, most especially when they are already nearing menopausal years.

Besides popping a pill or medication for this or just blindly accepting what fate had in store for you, here are some of those workouts that allegedly can help induce your body to increase its testosterone production.

bodybuilder muscles

Testosterone-increasing workout #1: HIIT Workout

By engaging oneself to a HIIT program or high-intensity interval training, according to several in-depth studies about it, individuals suffering from reduced amounts of testosterone in his system can boost his body to produce more of this important hormone.

From one of the said studies, its results showed that people who had gone through an array of short but intense 6-second sprints tend to enjoy increased amounts of testosterone in their systems. Besides, testosterone levels tend to remain high even after the individual’s body has completely recovered from the sprint exercise.

Testosterone-enhancing workout #2: Lifting Weights

Much like how the HIIT workout goes, this type of physical exercise necessitates you need to push yourself to the limits to reap the beneficial effects they have on your body. Ideal workouts that fall into this include a heavy, full-body exercise in the form of deadlifts, squats and Olympic lifts. But you need to perform them at 85-95 percent of your 1RM or one-repetition maximum.

Testosterone-producing workout #3: Longer rest periods

Scientists have looked into this to know what short periods of rest can do on testosterone. They found out that long periods of rests, a minimum of 120 seconds, between sets are beneficial to the body in as far as building testosterone is concerned. It will still allow your system to build other important hormones too, including the growth hormone, even at shorter periods of rest.

highly intensive training

Testosterone-increasing workout #4: Engaging in forced reps

In a forced repetition, you need to do a weight-lifting exercise as much as the times that your body can. Then, with the help of a partner, have him assist you in carrying out several additional repetitions. This will be anywhere from 10-15 or more.

Best results from forced rep workout usually come most effective and high-impacting when you perform them with multi-joint movements with large-range-of-motion. For instance, you can perform barbell squats as a warm-up set.

Then, you can follow this up with a partner, or a personal trainer. Or anyone at the gym who is willing to help and assist you – pick out a weight that you think you can do a minimum of 5 – 6 repetitions on your own but will need you to be assisted by another to carry out 3-4 reps done right after. This should make you a total of 8-10 reps. You can do the cycle again anywhere from 2 – 8 sets.

If you will try to incorporate the above-mentioned testosterone increasing workouts, do your best to get adequate amounts of sleep. Otherwise, all that hard work you did at the gym will just go down the drain right after.

If you are still too concerned with your T-levels, the best course of action you can take here is to have them looked into by a physician. You may not be putting yourself in harm’s way when you perform any of the above-mentioned exercises regardless if your system happens to have low or adequate testosterone, but if your situation happens to show you have an extreme T-level amount, that is either very high or low testosterone, it may take your body more than just doing a good exercise to help it in balancing the problem.

If you are in this type of situation, reaching out to a reputable TRT Australian doctor will help you best in getting to the bottom of the issue, right even before it escalates to a bigger health problem.

How is Waterjet Cutting Technology Used in the Medical Scene?

| Advance Medical Equipment, Latest Technology

The first acknowledged use of waterjet cutting technology in the medical sphere was when it was utilized for cutting bodies and as an indispensable tool for endoprothesis dental surgery. One of the advantages of the water jet method of cutting over other traditional cutting methods is that it does not involve the use of or generate heat, pressure, or sound. Hence, one good reason why it is ideal for dental and medical surgery.

surgery tools scalpel

Another good thing about it is that it lessens the need for anesthesia, promoting healthier dental tissues when applied for dental procedures. The tendency of the waterjet method when utilized for a dental procedure is to leave a relatively dry work area. This works to the advantage of a dental specialist who needs to carry out a subsequent hole filling because it mitigates micro-cleavage risks and jagged teeth.

The water jet technology can be used practically in traumatic wound cleaning. Skin wounds of this type and their healing process are codified using the abbreviation, “TINE”. This stands for tissue necrosis, which indicates dead skin tissue.

Damaged and dead tissues, including the inadequate supply of blood, need to get removed. As for the bacterial burden, it should not go greater than 100,000 bacteria/g. The use of waterjet and making it work as a scalpel will pave the way for healthier tissue as opposed to the use of traditional methods. Known as the versajet technology, this is also highly recommended when you need to clean wounds and clear them from foreign elements including silicone gel brought about by implants, sand, and earth. They could otherwise get integrated into the skin’s healing process, thereby creating a tendency to create and leave a traumatic tattoo.

Waterjet cutting technology has also found practical application in skin graft degreasing. Liposuction is another field where this technology is likely to receive a practical application. Water jet liposuction (WJL) is a qualified non-edema method, maximizing the old method’s benefits.

WAL or water jet assisted liposuction makes use of a thin fan-shaped stream of water. By this measure, the process is made able to release fat cells while saving the nerves and blood vessels. Fat cells will then be removed from where they got accumulated, only to get drifted out by saline. There is a handful of benefits to enjoy from WAL, and they are as follows –

It offers greater accuracy of results, sans contour changes, and edema.
Improved patient mobility of patients
Optimal access to the treated area
Improved patient comfort
Postoperative wound infiltration is made possible in less than 24 hours.
Amount of patient medications is reduced

Moreover, the hydro abrasive jet is also considered as a very indispensable dermatology tool used in the removal of dead skin cells. Water flow will be dosed with several kinds of drugs, included here would be anesthetics, to help in the removal or alleviation of pain; antiseptics, for disinfection purposes due to the violation of the skin integrity.

Another water flow application in medicine is the microwave waterjet cutting scalpel. This technology is normally used for the resectioning of tumors. When you combine a jet system and the microwave scalpel technologies, the result of the melding is this kind of technology that allows flow control directly into the saline, then directing it towards the workspace.

Microwave waterjet scalpel lowers the odds of perceived microwave radiation risks to occur. Its direct usage in medical surgery brought out many benefits and advantages that are not to be seen with other traditional methods. It utilized sensitive sterile saline pressure to be able to resect tissue. The applicator is made up of a nozzle jet with a 120-micrometer diameter.

Why You Need A Timber Ceiling Fan in Your Home

| Home Improvement

A ceiling fan is able to increase coziness and reduce the energy bills of yours in the summer as well as winter. Here’s a guide in order to help you acquire the best ceiling fan for the home, and then to share the cost-saving advantages of utilizing ceiling fans all throughout the season.

bedroom ceiling fan

Timber Ceiling Fan and Energy Saving

Ceiling fans are really economical to use. The majority of ceiling fans cost only three cents every hour to work – exactly the same as a 60-watt light bulb. An hour, in contrast, that is dramatic, air conditioners utilize 2000+ watts.

Everyone knows that in the temperature during mid-summer and a fan just will not cut it by itself. But in case you make use of a ceiling fan in combination with an air conditioner you are able to create a saving of up to 40% on energy expenses to cool the home of yours. Think about the savings for the planet also.

Cooling

The breeze produced by a ceiling fan is going to make you feel as much as eight degrees cooler.

Summer just passed so fast into autumn – even though you would not know it right here in Australia just still as the temperatures continue to be really summery and above thirty Celsius most days. You may have your fan on during day time while I work and I have been able to considerably scale back on the usage of our air conditioner since looking into this post.

Heating

It was an eye-opener. Did you realize that in case you have a reversible fan you are able to alter the blade direction to anti-clockwise and reduce the heating costs of yours in winter? The reverse activity of the blades drives the warm air from the heater of yours up to the ceiling then back down the walls, re-circulating the warm air and leading to energy savings of ten %.

What to Consider when Purchasing A Ceiling Fan

Room Size

For a big room – six x six meters (20-30 square meters or perhaps 225 400 square feet) – you will need a fan with cutting blades of 132cm or over. Smaller rooms up to four x five meters (twenty square meters or perhaps 225 square feet) merely demand 122cm blades.

concorde II ceiling fan

Room Usage

A timber ceiling fan is actually quieter than people with metal cutting blades since they move less atmosphere. When you are searching for a ceiling fan for a peaceful zone in the home such as the bedroom or home office, pick timber. Metal blade fans are going to serve you well in places that are generally noisier like the kitchen and living spaces.

Blades

There is really a very small variation in the overall performance of fans with 3, 4, or 5 blades. So, base the choice of yours on the appearance of the design and the taste of yours.

Considering these things before deciding to install a ceiling fan will make sure that you won’t end up wasting your money, time, and effort.

What Do We Need to Know About Yagi Antennas?

May 21, 2020

| Advance Medical Equipment, Communication Technology

Yagi antennas are also known by another name, Yagi Uda antennas. They are the same directional antenna technology consisting of several parallel elements in a line.

The yagi type of antenna is named after its two Japanese national inventors, Hidetsugu Yagi and Shintaro Uda. It usually comes with a reflector element and normally this is slightly longer when compared to that of a driven dipole. Now, as for the directors, they are a bit shorter.

The radio waves, which can be traced as coming from the driven element, are being absorbed and reradiated by the parasitic element with a different phase. This will help modify the radiation pattern of the dipole.

The waves that are coming from the multiple elements will create interference, paving way for the coming of enhanced single direction radiation. This helps a lot in increasing the antenna gain as opposed to just having a simple dipole.

yagi beam

Basics of the Yagi Antenna Theory

If you are keen to know and want to understand the Yagi theory and what it is like, good background info on the phases of flowing currents is essential here.

The yagi type of antenna and its parasitic elements work by re-radiating the signals they have in a different phase to help in matching that of the driven element. This makes it possible to have that signal reinforcement occur in some directions but would be canceled out in others, instead.

While there are a few antenna Yagi elements that are not directly driven but are rather picking up the driven element’s power, all these extra elements are qualified as just parasitic elements.

The design in which the Yagi type of antenna comes in has its own set of limitations — the additional element’s power is not driven directly. There is no guaranteed way that the induced current phase and the amplitude can be controlled or managed in any way. They are dependent upon their spacing and the length between the dipole or the driven element comes in.

What does this signify then? This only goes to show that canceling in one direction is not at all possible. Nevertheless, one can still possibly obtain an elevated degree of reinforcement in one direction and this should earn you still a high level of gain.

Additionally, this also brings a high cancellation degree in another, providing you with a good front to back ratio. Yagi antennas are highly capable of providing useful gain levels.

To have that required phase shift, it’s essential to come up with an element that can be made, falling as either capacitive or inductive. The type of reactance that it should come with is likely bringing along as well a different effect.

Inductive:

Once a parasitic element is transformed so they become inductive, the tendency of the induced phase will reflect the power but it will not be in close range to the parasitic element. This will make the RF antenna radiate an increased level of power, only that it is in the opposite direction of the parasitic element. An element behaving this way is referred to as the reflector.

Capacitive:

If you make a parasitic element as capacitive, the induced currents will be in a phase where the power of the whole antenna radiated will be towards the parasitic element’s direction. The element displaying this kind of behavior is known as the director.

You can make it capacitive, but you will have to tune it above resonance level. It is made possible when you add capacitance to the element, which has to be in a capacitor form. Or by having it 5% shorter when compared to that of the driven element.

By deliberately adding more directors, it will tend to increase the antenna’s directivity. This will increase the gain but will be inversely proportional to the beamwidth which is reduced. The successive director’s length will be reduced slightly.
