Marine VHF radio uses the radio frequency range between 156.0 and 162.025 MHz, called the VHF maritime mobile band. 

A VHF station consists of operator site, transmitter/receiver site, Antenna sites and connection between the various sites. 

A marine VHF set is a combined transmitter and receiver (transceiver) and operates on standard, international frequencies known as channels. Channel 16 (156.8 MHz) is the international calling and distress channel. 

VHF Coast Radio Stations require "Digital Selective Calling" (DSC) capability, to receive and relay e.g. distress signals. 

Transmission power up to 100 watts, give a maximum range of about 40 nautical miles (75 km) with aerials mounted on hills. Frequency modulation (FM) is used, with vertical polarization, meaning that antennas have to be vertical in order to have good reception.
