All You Need to Know About UHF Antenna

Finding the right antenna can be tricky. But you need to understand the working and benefits of several kinds of antennas to choose the right product. UHF Antenna is widely used in applications such as TV broadcasting, Bluetooth, cell phones, and Wi-Fi. It has a smaller size than the VHF antenna and shorter wavelengths as well.

UHF antennas help to connect through a single frequency of 477MHZ. This blog highlights the facts about UHF antennas, their benefits, working, and other things.

Importance of Using an Antenna

Using an antenna for radio is very necessary to hear incoming transmissions precisely. How you mount an antenna also decides its performance. Mounting an antenna at a lower height will affect the quality of radiation.

You must find a high-quality UHF FTS antenna to get smooth communication. It is necessary to test your radio by using this antenna.

Main Elements of UHF Antenna

After discussing a short section on UHF antenna, let us have a look at some of the major elements of this antenna in detail:

• Height of the Antenna

The height of an antenna plays a vital role in improving its performance. A tall UHF Antenna gives better communication than short antennas. But do not choose a very long antenna as it can create hurdles and take up a lot of space in your home or car parking area. So, you must pick an antenna with a normal height and length to gain better communication on your radio or mobile phone.

• Antenna Base

The next important element in the antenna is the base. In simple terms, the base of the antenna is how your antenna is connected to the motor vehicle and how the coax cable is attached to your aerial.

If the antenna is ridged, you must attach a whip to the base. This whip is important to enhance movement while trekking in a bush.

• Gain

Another important element of a UHF ATC Antenna is Gain. This factor is measured in dB which is decibels. It is a very important thing for trekkers who are traveling to the countryside and remote areas.

• Cable Lengths 

In the case of cable lengths, the important thing is the quality of the cable. If you are using a cheap quality cable, it will not work for a long time and also give poor performance. So, the best thing you must do is to pick a short cable and choose the best quality coax cable to reduce signal loss or noise while transmitting the data. It is necessary to buy the best quality cable to get a nice performance.

• Flexibility of Antenna

The flexibility of the Jammer Antenna depends on the type of materials used to design an antenna. Using a whip is very necessary to enhance the antenna’s performance. So, you should choose a flexible antenna that suits your requirements.

• Location of Antenna

The location of the antenna is very important. How you mount the UHF Anti Drone Antenna is also important. The location of the antenna affects transmission ability. The best location to mount an antenna is the center of the roof. It gives strong signals in all directions.

In addition, the antenna must be mounted as high as possible to enhance its ability to see. You can communicate effectively by mounting an antenna at a higher position.

Kinds of UHF Antennas

UHF antennas are of various kinds with different designs and lengths. Read on to know the different kinds of UHF antennas:

• UHF Yagi Antenna

Another name forthe UHF Yagi antenna is Yagi-Uda Antenna. It has a dipole. Apart from that, the amplitude and phase are also dependent on the spacing and length between the dipole. Some of the elements in the UHF Yagi antenna include a Reflector, a driven element, and a director.

• Log Periodic Antenna

The next type of UHF antenna is Log periodic antenna. It was invented by John Dunlavy in the year 1952. It is somewhat similar to Yagi Antenna and can operate over a wide band of frequencies.

Some of the most types of Log periodic antennas include Slot, Planar, Trapezoidal, Dipole, Zigzag, and V-Type. In this type of antenna, the physical and electrical characteristics are repetitive in nature. Moreover, this antenna has unidirectional or Bi-directional radiation patterns.

• Fan Dipole Antenna

In the Fan dipole antenna, every dipole shows low impedance at the Feed Point at its resonant frequency. When the frequency travels away from one dipole’s resonant frequency, impedance increases.

This antenna has several frequencies and every frequency corresponds to the frequency of different Dipoles.

• Conical Array Antenna

The next type is the Conical Array antenna. This type of antenna has a conical structure with cross-slot radiators fed by a Feed network that gives controllable amplitude and phase excitations of each arm of the crossed slots.

Where are UHF antennas used?

The full form of a UHF antenna is an Ultra High-frequency antenna. These antennas are widely used in the following applications:

1. TV broadcasting, land mobile radio systems, mobile telephones, and digital television.
2. UHF High Gain Antenna is also used for voice communication in the military field as two-way Radio.
3. One can use UHF radars to track enemy fighter planes or bombers during war times.
4. UMTS and GSM mobile phones use UHF cellular frequencies. They help to use cell phones and mobile computing devices to a public telephone network and the Internet.
5. UHF Military Discone Antenna is used in many other devices.

Final words

These are some facts related to UHF High Gain Helical Antenna, its working, and its types. You can find a reliable UHF Antenna manufacturer online from the official website. 

A High Gain ATC Antenna has short bandwidth with high frequency. The size of the antennas for reception and transmission is related to the radio wave and size. UHF antennas are also shorter than VHF antennas and are widely used in different applications and devices.
