Антенны уличные для радио УКВ, FM
VHF antennas are a crucial part of your VHF installation, and understanding how they work and how to select the correct antenna can greatly improve your ability to communicate with other boaters and shore stations. The main purpose of a VHF antenna is to provide a radiator for the power that the transmitter in the radio produces, and to radiate this energy in the correct direction. Antennas also have to be enclosed in a weather-protected enclosure or be made of a corrosion resistant metal and plastic and must be able to withstand the substantial forces generated by a boat pounding in heavy seas. Antennas with a high dB rating concentrate energy perpendicular to the antenna shaft in a field that is shaped like a disk.
