What Makes UHF Antenna Signal Frequency Distinct From VHF Antenna Signal?

Understanding the differences that exist between VHF (Very High Frequency) and UHF (Ultra High Frequency) signal frequencies will help you identify the right signal frequency for your two-way radio. UHF antenna signal, for example, does not go far enough as VHF antenna signal does but may allow greater bandwidth occupation. 

Operating frequency is used by all cellular networking devices. This also includes two-way radios and mobile phones. In conjunction with the equipment used to communicate via them, they can be managed and controlled to a certain extent by the authorities and the government.

Since people use multiple kinds of radio signals, a broad variety of wireless equipment is necessary to reach these specifications.

The Federal Communication Commission, otherwise known as the FCC, regulates the use of radiofrequency bands in the United States.  

The FCC is the one body that will decide which parties can operate in each band and whether anyone would be given priority over other operators. Main consumers here include duly licensed radio and television broadcasters, together with commercial communication service providers like mobile phones and two-way radios.

VHF stands for Very High Frequency

Very high frequency is widely used in many different applications like data transmission, two-way land mobile radio networks, long-distance FM radio broadcast, and maritime communications, to name a few. 

VHF antenna radio waves vary in frequency, starting from 30 MHz up to 300 MHz.

VHF waves must not go beyond the local radio horizon which is 100 miles. In addition, it is unlikely that VHF frequencies are to get disrupted by problems associated with electrical equipment, ambient noise, a host of other kinds of interferences. 

VHF frequency is divided into different bands, including low-band and high-band. Cordless phones, wireless microphones, radio-controlled toys, and other similar devices operate in the low-band VHF range of 49 MHz. 

A slightly greater VHF range of 54-72 MHz runs television channels 2-4, together with qualified wireless “assistive listening” devices. Channels 5 and 6 work on VHF frequencies 76-88 MHz. 

Due to the high level of radio “noise” in which these frequencies come in, low-band VHF antenna use is not encouraged in serious applications. Despite the probability of having background noise, it still managed to become one of the most sought-after options because it is seen as a much cheaper equipment.

If you are using an assistive listening device that works in the 72-76 MHz range, transmission capacity is reduced to less than 50 mW. A large UHF antenna booster is also necessary. This can come to about 3 feet long, thus limiting portability.

UHF Ultra High Portability

Compared to VHF radio waves, UHF radios are relatively shorter, measuring anywhere between 12 to 24 inches only. Consequently, this will lead to the reduction of the antenna length and thus also decreasing the radio range.

As a result, you will see a broader frequency spectrum and even a broader range of audio signals. Power levels of up to 250 mW are tolerable, exceeding the VHF power limits of 50 mW. 

The low-band and high-band UHF frequencies overlap; the low range is anywhere between 450-536 MHz while the high range is set at 470-806 MHz. These frequencies are usually dedicated only for business solutions while UHF television channels normally run from 14 through 69.

High-band UHF, that is anything beyond 900 MHz, has the least amount of disturbance and this will include UHF antennas that measure from 3 up to 4 inches. These channels run studio-to-transmitter connections as well as other primary channels and users. 

What are the Different Kinds of UHF Antennas or UHF Aerial Installation Antenna?

In places where cable TV lines or satellite signal receivers are not available yet, the presence of UHF antennas will come as very indispensable and versatile equipment to have. Not very long ago, we could make use of almost anything to get ourselves a better television reception.

All it takes is just a little ingenuity and you can have your TV set reception working well. If you have a coat hanger or some metal rods, they can help do the trick of fixing the reception on your boob tube. 

When digital signals took over, the use of improvised devices was displaced. It is put into oblivion. Nowadays, such measures are no longer applicable because they have become obsolete. 


There is another term for which UHF aerial antenna is known for, the ultra-high frequency antenna. The design in which this type of antenna comes in is primarily intended for receiving radio signals as well as other mobile phone signals, even WiFi signals.

While they are commonly used for television broadcasts, this type of antenna can also pick up different kinds of broadcast signals including high definition channel broadcasts. 

And even if it is common to see VHF antennas or high-frequency antennas to come in a rabbit ear design, they are a foreshadowing of UHF antennas. 

We have a couple of types of UHF antenna and some of them can be easily distinguished from one another, but here are some to help you decide on what could be the most appropriate to have on your TV set. 

Different Kinds of UHF Antenna 

Whip UHF Type of Antenna. 

This type of antenna (UHF) is made from a single metal rod attached to a single conductor. By the sheer design in which they come in, we can safely say that they are more appropriate for use in old models of mobile phones, walkie-talkies, and automobiles for radio signals. These devices too have their whip antenna mounted inside of them. 

When whip antennas undergo modification, they can be made into loop antennas where the single metal rod is being looped so they can be attached to 2 different conductors instead.  

Bow Tie Antenna

The bow tie antenna is the better alternative for use in television because they help enhance the reception. Similar to how the loop antenna is made, they usually come with 2 conductors although they don’t resemble a bow tie (contrary to its name). 

Instead of the two conductors attached to the antenna, it is composed of 2 antennas. Every single one of those is made to attach to one and separate conductor. 

communication sattelite

Compared to a manifold of other new antennas, this is relatively weak. It can be used indoors, however, you can’t have high hopes that its signal strength will be that intense. But you can take advantage of some reflectors to further enhance its strength

Yagi Uda Antenna

The more appropriate application for the Yagi Uda antenna is for UHF aerial installation. This variant was invented by two Japanese professors, Hidetsugu Yagi and Professor Shintaro Uda.

The reason behind the popular use of this type of antenna can be attributed to the fact that it is primarily designed to receive UHF signals. 

While it is only capable of picking up signals coming only from a single direction, the moment that you have properly aligned it to the right direction, it will be able to pick up strong signals and properly transmit them. This explains the reason why it is usually seen on house rooftops.
