Coaxial Cable; Emergency (Channel 16 Use) - Standard Horizon Explorer GPS GX1700 Owner's Manual

5.3.1 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-8X 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.
