The Advantages and Disadvantages of Ultra High Frequency (UHF) Radios

Ultra high frequency (UHF) waves are the designated frequencies in the range between 300 megahertz (MHz) and 3 Gigahertz (GHz). The frequencies above this range fall into the SHF (super-high frequency) range or the Microwave frequency range.

UHF radios are commonly used as a form of communication between two or more individuals. However, the “Electronic Access Control” requires that UHF radios users need to have a licence in most parts of the world.

There are a variety of different radios and frequencies that you can use and there are many different applications for each of them. In this blog however, we will be listing the different types of advantages and disadvantages of the UHF radios.

UHF Radios are often known for their portability and capability because they are relatively small in size and they work in almost any weather condition. Their ultra-high frequency waves have the ability to penetrate through most natural obstructs such as trees and man-made structures such as buildings.

They also have a wider spectrum of UHF waves. What this does is it prevents or eliminate the possibility of intersections between frequencies amongst users. This improves the user experience by ensuring stable connections.


GME have quality compact UHF radios that are the first of a new generation of connected UHF radios. Technologies today have advanced to the point where UHF radios have access to app control with features such as creating and sharing scan lists. Additionally, you can also get instant access to the entire Australian and New Zealand registered analogue frequency database which acts as a portable database for the user’s convenience.

This is known as the XRStm Connect App which combines easy navigation menus with the smart device control technology. This keeps the user up to date with any changes or updates which improves usability considerably.

One of the main disadvantages of the UHF radios is that their frequencies are highly dependent upon the line of sight. Generally, the UHF radios also suffer from interferences from nearby TV stations that also rely on the ultra-high frequencies. Furthermore, since they have an extensive range of communication, this affects their battery power to a degree because of the amount of power it requires to conduct long-range communication.

The frequencies are also generally assigned to various governmental agencies and groups who wants to use it to their own benefit which restricts other users from sharing the same frequency.

Therefore, it is important that you check the licensing in your area in order to avoid any problems.

It is important that when choosing a two way radio communication equipment, you weigh the pros and cons of the products thoroughly. You must understand what the purpose it is going to serve so you can choose the most suitable products for your needs.

The level of obstructions, the range, the frequency and the battery life etc., are extremely important to take into consideration, which is why it is best to choose a trusted brand to deliver the best qualities.
