Marine VHF Combines Transmitter and Receiver
Tuesday, January 26, 2010
The VHF Marine Radio features a built in ability to both transmit and receive communications. Typically they operate within a frequency range between 156 and 174 MHz. Channel 16 (156.8 MHz) is the international calling and distress channel. Transmission power ranges anywhere from 1 to 25 watts. What does this mean in terms of distance when one broadcasts? If the broadcast is from a tall antenna to tall antenna, that signal could be picked up as far away as 60 nautical miles. If you are using your VHF Radio on a small boat, your range will probably only be about 5 nautical miles.
