VHF stands for "Very High Frequency" and UHF stands for "Ultra High Frequency." UHF has two ranges, low band (operates on 378-512 MHz) and high band (operates on 764-870 MHz). VHF also has two ranges, low band (49-108 MHz) and high band (169-216 MHz). Both bandwidths have distinct advantages and disadvantages depending on the application. VHF is typically better for long ranges with no obstructions (walls, equipment) and is best for use outside in open spaces. UHF frequencies are preferred inside facilities because the frequencies are shorter and can move around corners and turns more effectively. Most two-way radio users would benefit from UHF.
