VHF Antennas

Little help for VHF marine radio antennas and connecting elements.
A transmitting and receiving system is basically composed of three parts, forming a system. Firstly, it is a radio itself, the coax cable with connectors and plugs and the FM antenna.
Often the cable and the connections are given the least attention. But these components are also an important part of the system and therefore should be selected accordingly to the requirements (a chain is only as strong as its weakest link). For FM antennas the principle applies, that the range is increased by the height of the antenna. Similarly, the range increases also with the gain, which is expressed in dB. However, care must be taken during reinforcing, since with increasing dB-transmission the transmitter radius weakens. Therefore it is recommended, as for antennas mounted on the mast of sailing yachts, to choose a lower dB-number, as these leave despite large fluctuations a uniformly strong signal.
 
Motor sport boats and yachts are due to the small height not exposed to strong fluctuations and therefore mostly use long rod antennas. For amplification, the golden middle is chosen around 6 dB mostly. Usually the mounting onto antenna feet or holders is done with a  ¾“ threaded connection (AG).
