There are two main options when choosing a two-way radio, VHF or UHF. Many people do not understand the differences between these two frequency ranges, however, they should so that they will be able to more effectively choose the right option to fill their communication needs. When trying to decide which system is right for you, most people look at these important factors: where they will be used, how they will be used, for what purpose or application they will be used, and how much they cost. Location can definitely be a huge factor when deciding between UHF and VHF. VHF radios have less available frequency spectrum, which translates to less channels and more congestion. In urban areas, or places with a lot of industrial equipment, UHF provides a smaller chance of interference than VHF. This is due not only to the greater amount of available channels on UHF but also due to the fact that VHF is an older technology and thus, more devices operate using VHF frequencies and could potentially interfere with each other. In turn, in areas with less obstructions VHF can provide a greater range than UHF.

          VHF systems typically operate on bands from 100-170MHz and UHF operate on bands from 400-500MHz. The VHF bands are more crowded with users, and thus are more likely to have interference. Also, the higher frequency UHF bands have smaller wavelengths, which allows for smaller antennas. Finally, the higher the frequency, the better the signal will be at passing through obstructions.

          As you can see, both UHF and VHF have their relative strengths and weaknesses. Depending on how you intend to use your radios, either one may be the better option for you.
