8. INSTALLATION
8-3
8.3 Coaxial Cable
The VHF antenna is connected to the transceiver by means of a coaxial cable - a
shielded transmission line. Coaxial cable is specified by its diameter and construction.
For runs less than 6 m, RG-58/U, which is approx. 1/4 inch in diameter, is a good
choice. For runs over 6 m but less than 15 m, use the larger RG-8X or RG-213/U. For
cable runs over 15 m, use RG-8X. See the figure below for how to attach the connector
the cable.
To get your coaxial 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.
8.4 Electrical Connections
Connect the power cable, handset and antenna to the radio. The antenna and power
supply connections are as follows:
1. Mount the antenna at least 1 m away from the radio. At the rear of the radio, con-
nect the antenna cable. The antenna cable must have a PL259 connector at-
tached. Use coaxial cable RG-8/U if the antenna is 7.6 m or more from the radio.
Use RG58 for distances less than 7.6 m.
2. Connect the red power wire to the positive terminal of the power source. Connect
the black power wire to a negative ground.
3. Connect the handset to the remote connector on the rear panel.
4. If an external speaker is used, refer to section 8.5 for the connection.
5. It is advisable to have a certified marine technician check the power output and
the standing wave ratio of the antenna after installation.
