All about the Yagi Antenna

Yagi antenna is widely used in the field of radio broadcasting. What should we know about the Yagi Antenna? Let's have a brief understanding of the Yagi Antenna first.

Binavî

A Yagi antenna is a type of antenna array, which consists of two or more parallel resonant antenna elements. To make a Yagi antenna, it often needs a single driven element that is connected with a transmitter like an FM radio transmitter through a transmission cable and additional "parasitic elements" without an electrical connection. And it usually includes a reflector and any number of directors.

Applications

As it is featured by the capability of high gain and directional, it is especially suitable for point-to-point transmission, TV transmission, and low-power radio signals transmission. For example, for FM broadcasters, it can be used in the FM signals transmission from FM studio to FM radio station. It can greatly improve the FM signals.

Pîvan

As its simple construction, it doesn't need too many materials to build up, which comes with lightweight and low wind load. It means that it has an excellent capability of wind resistance.

Biha

The Yagi antenna is probably one of the most price-performance antennas. Without too much cost, you can buy a Yagi antenna with great performance. Even if you need to build an orientational antenna array, you just need to combine four Yagi antennas together.

Qezenc

For a Yagi antenna, the capability of improving the radio signals depends on the number of elements. The more elements it has, the better it can improve the signals. A Yagi antenna's gain can reach up to 20dBi, especially for low-power radio transmission and point-to-point transmission.

Lêkirinî

Due to its simple structure, everyone can install the Yagi antenna easily and transport it conveniently. At the same time, it can also be combined into an omnidirectional antenna array at any time according to needs, which is especially suitable for professional FM broadcasters with complex and diverse requirements.

1. Q: How Long is the Driven Element of a Yagi Antenna?

A: The driven element is equal to 1/2 wavelength.

The approximate length of the driven element of a Yagi antenna is 1/2 wavelength. So if you use the Yagi Antenna in the higher frequency range, the elements are shorter.

2. Q: How does a Yagi Antenna Work?

A: A Yagi antenna works through the interaction of four essential pieces.

• Driven Element - The point that the Yagi antenna connected with the feed line.
• Derhêner(ên) - Used to provide the antenna with directional power and gain.
• Xet - It is the spine of the antenna and is used to hold the directors and reflectors and connect to the driven element.
• Reflector - It is used to reject signals outside its range and amplify what’s inside.

3. Q: What is the Range of a Yagi antenna?

A: It works in the frequency range of 3 - 3000 MHz.

Yagi antennas can be used in the frequency range from about 3 - 3000 MHz, with the best operating range below about 1500 MHz.

4. Q: Is a long high gain Yagi antenna suitable for digital TV?

A: The answer is YES.

But you should note that a Yagi antenna is hard to have high gain while having enough bandwidth to cover enough UHF channels. The frequency range of the Yagi antenna is quite narrow.

With a Yagi antenna, no matter you are planning to use it in studio transmitter link system or provide FM/TV broadcasting services to the public with it, you don't need to worry about the quality of the signals. If you need to buy a Yagi antenna, têkilî FMUSER niha!
