ABOUT VHF MARINE RADIO
The radio frequencies used in the VHF marine band lie between 156
and 158 MHz with some shore stations available between 161 and 163
MHz. The marine VHF band provides communications over distances
that are essentially “line of sight” (VHF signals do not travel well through
objects such as buildings, hills or trees). Actual transmission range de-
pends much more on antenna type, gain and height than on the power
output of the transmitter. The approximate distance a portable 5W radio
may communicate is about 5 miles in if there are no obstructions (build-
ings, hills etc.) restricting line of sight transmission.
