VHF

VHF, or Very High Frequency, equipment operates in the frequency range from 30 to 300 MHz within the radio spectrum; however, in the context of land mobile radio (LMR) usage the VHF Band falls within 136 – 174 MHz. In addition to LMR usage (which includes public safety, business and military users), common VHF uses include FM radio broadcasts, analog TV, civil aircraft communications, and Marine VHF radio. VHF radio has been in use since the 1930's, whereas newer two-way communications systems tend to use frequencies in the UHF - frequency band ranges, where there are more available channels.
