Advantages and Disadvantages of Yagi Antenna

The Yagi antenna is invented before few years by Japanese inventors. It is used in ham radio, TV, and other devices for communication. You can use this antenna to connect a site to a Wi-Fi access point. The dipole in this antenna works as a main radiating element. Apart from that, it also has a reflector behind the radiating element.

You can add extra directors to the antenna to get 1 DB of gain. Some parasitic elements can be also added to change the performance of the antenna. These elements are placed new to one another for better performance.

Using a High Gain Yagi Antenna has many benefits and drawbacks. This blog lists the advantages and disadvantages of a yagi antenna in detail.

Advantages of Yagi Antenna

High-quality Polarized Yagi Antenna is used for communication purposes. It is also used in several devices such as TV and ham radio. This antenna has several benefits such as:

• Helps to Receive Strong Signals

Powerful signals help to communicate well on mobile phones. Yagi antenna is a type of directional antenna that contains a beam width between 50 and 70 degrees Celsius. Apart from that, you can also use VHF Yagi Antenna with several omnidirectional antennas to get a high gain.

Installing a Yagi antenna will help to gain stronger and better signals while communicating on mobile phones or watching TV. One can use these antennas in commercial and residential areas as well.

• Gives a Good Range

High Gain Circular Yagi antenna is small and compact. It also contains a high gain that helps to get a good range while talking on mobile phones or watching TV or listening to ham radio. Because of their physical size, yagi antennas work better than log periodic.

You will get better communication after installing these antennas in your office building or homes. A good range is one of the major benefits of using a Yagi Antennafor various purposes.

• Removes Signal Noise

Communication is very important in border areas and military zones. Many ordinary antennas do not give proper communication at these places because of poor range. UHF Yagi Antenna is ideal to use in border areas and military zones. It removes signal noise while delivering important messages to military teams.

In addition, Yagi antennas are useful for powerful communication in commercial places. They remove background voices while talking on mobile phones and other devices. Many telecommunication companies use Yagi antennas in making the latest mobile phones.

• Simple to Mount

Yagi antenna has a beautiful design that makes it easy for you to mount anywhere. You can mount yagi antennas on any military vehicle or a pole. Besides, the construction of yagi antennas is also solid to protect them from rust.

Yagi antennas do not get damaged due to rains, UV rays, dust, smoke, or pollutants. You can install these antennas in any commercial or residential area for communication and entertainment purposes. Simple mounting is a benefit of buying yagi antennas.

• Affordable Antenna

Yagi antenna is more cost-effective than log periodic antennas. Apart from that, it is also simpler to use a yagi antenna than log periodic antennas. One can use yagi antennas anywhere in commercial or residential buildings. Moreover, the assembly of yagi antennas is simple and not complicated like other antennas.

• Easy to Build an Antenna

Another benefit of the yagi antenna is that it is simple to build anytime. All you need is a Yagi circuit printed board and some simple rods to design yagi antennas. This is the reason why these antennas are used widely in telecommunication companies and military zones.

These antennas give more directivity than simple dipole antennas. The unidirectional radiation pattern of yagi antennas helps them to give powerful signals in every direction. They are also simple to mount on vertical and horizontal poles with the help of simple equipment.

• Simple to Maintain  

Yagi antennas require less cost or no cost of maintenance. Once installed, you do not need to spend money to maintain yagi antennas. They also work anywhere and in every kind of weather. Even rough handling does not break a yagi antenna. You can maintain a High Gain Dual Stacked Yagi Antenna for a long time.

Disadvantages of a Yagi antenna

With many benefits, the Yagi antenna also has many drawbacks such as:

• Require a Huge Number of Elements

A High Gain Quad Stacked Yagi Antenna needs several elements such as radiating elements to work. You must combine many elements and add extra directors to use these antennas. Extra directors help to get gain in yagi antennas.

• Director Elements Reduce Bandwidth

One disadvantage of using a Dual Stacked Circular Yagi Antenna is that it loses its bandwidth by adding more director elements. As a result, the signals became weaker and weaker while talking on mobile phones or watching TV channels.

• More Antennas for More Gain

Yagi antennas have several drawbacks when used for telecommunication or entertainment purposes. If you want to get a high gain level, it is necessary to take a long Yagi antenna. But a long antenna also comes with a limitation. It can give a gain of between 6 and 9 dB and you will have to add one more Yagi antenna to get a higher gain level.

• Fail to Work from a Far distance

Yagi antennas give low performance as you move away from the range of frequency. You will not get signals while communicating on phones or listening to ham radio.

Final Words

You can use a Quad Stacked Circular Yagi Antennato get a high gain and perfect direction. It is suitable for all those applications that work on gain and direction. With several advantages and drawbacks, yagi antennas are still good for regular use. They are simple to build and mount anywhere. These antennas also need a low cost of maintenance when compared to other kinds of antennas. Yagi antenna can be mounted with the help of simple and basic fixings.
