Wireless Microphone System Buying Guide VHF vs. UHF. Virtually all pro wireless systems operate on either the VHF (very high frequency) or UHF (ultra high frequency) bands. VHF wireless systems generally operate within the 174 to 216MHz range (the range of TV channels 7-13), while UHF uses the 470 to 805MHz range (the range for TV channels 14-69).

VHF radios provide two-way communication and have a maximum range of up to 60 nautical miles. Owning a VHF radio is vital for marine safety. They are much more reliable than mobile phones and are the fastest link to rescuing agencies like the Coastguard, towing services or the harbourmaster.
