When looking for a two-way radio you’ll come across terms like UHF and VHF. UHF stands for Ultra High Frequency and VHF stands for Very High Frequency. These are different bands of radio frequencies with UHF being in the 300 MHz and 3000 MHz range and VHF in the 30 MHz and 300 MHz band.
The question most people have is which is better, UHF or VHF. The answer is neither and both. It depends on how and where you want to use them.
To give you a quick and dirty generalization, if you are planning on using your two-way radios mainly inside buildings, then UHF is likely the best solution for you. If you are mainly using your two-way radios for communication outside, then VHF would be a good choice. Either radio technology can work for you if you don’t really have a long range to cover. In that case you may want to choose VHF for it’s lower cost.
