Coaxial Cable - Standard Horizon ECLIPSE DSC+ GX1200E Owner's Manual

5.2.1 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 6 m, RG-58/U (about 6 mm in diameter), is a good choice.
For runs over 6 m but less than 15 m, the larger RG-8X or RG-213/U should
be used. For cable runs over 15 m 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 are supplied with the connector.
Be sure to make good soldered connections.
