COAXIAL CABLE
VHF antennas are connected to the transceiver by means of a coaxial cable
– a shielded transmission line. Coaxial cable is specified by it’s diameter
and construction.
For runs less than 20 feet, RG-58/U, about 1/4 inch in diameter is a good
choice. For runs over 20 feet but less than 50 feet, the larger RG-8X or RG-
213/U should be used for cable runs over 50 feet RG-8U should be used.
For installation of the connector onto the coaxial cable refer to the figure
below.
To get your coax cable through a fitting and into your boat’s interior, you
may have to cut off the end plug and reattach it later. You can do this if
you follow the directions that come with the connector. Be sure to make
good soldered connections.
