What are the Differences Between UHF and VHF Two Way Radios?

One of the most common questions customers ask us is what are the differences between UHF and VHF two way radios. It is an important question because both have different advantages and which type of radio you need very much depends on your circumstance.

Apart from some minor cosmetic details, there is usually only a subtle physical distinction between UHF and VHF two way radios….normally the antennas are slightly different in length.

In general, UHF radios are more suitable for indoor use because their wavelength is shorter and better able to penetrate through steel and concrete. They are also ideal in built-up areas such as shopping centres or office blocks. VHF radio signals tend to degrade more than UHF signals indoors.

VHF radios are better suited for outdoor use where line of sight or open terrain is involved. They are ideal for agriculture or at a festival or in rolling countryside.

When choosing a UHF or VHF radio, think carefully about your specific needs and pick the solution that best suits your situation. All of the Icom two way radio range is available in both VHF and UHF.

Summary of the differences between VHF and UHF two-way radios

UHF (Ultra High Frequency):

• Frequencies: 400 MHz to 470 MHz.
• Shorter wavelength, higher frequency.
• Better penetration through obstacles like buildings and foliage.
• More susceptible to signal loss in open areas with fewer obstacles.
• Ideal for indoor use and urban environments.
• UHF radios are commonly used in industries such as construction, manufacturing, and security.

VHF (Very High Frequency):

• Frequencies: 136 MHz to 174 MHz.
• Longer wavelength, lower frequency.
• Better propagation in open spaces and over water.
• Effective for outdoor and long-distance communication.
• Limited penetration through obstacles, making it less suitable for indoor or urban environments.
• VHF radios find applications in outdoor activities like hiking, camping, marine communication, and search and rescue operations.
