VHF Radio Frequencies
In the maritime context, VHF (Very High Frequency) Radio Frequencies refer to the range of radio frequency electromagnetic waves from 30 MHz to 300 MHz, with corresponding wavelengths of ten to one meters. Vessels use VHF radio frequencies for a variety of purposes, including communication between ships and shore stations, navigation, and emergency distress calls. The International Telecommunication Union (ITU) regulates the allocation of these frequencies to prevent interference between different users. In maritime operations, specific channels within the VHF frequency range are designated for certain uses. For instance, Channel 16 (156.800 MHz) is universally recognized as the international distress, safety, and calling frequency. VHF radio frequencies are line-of-sight, meaning they do not bend around the earth's surface or penetrate through significant obstacles, which limits their range but also reduces interference. The typical range for maritime VHF radio communication is about 20 to 60 nautical miles, depending on the height and power of the transmitting and receiving antennas.
