SG-2000 MANUAL 91

The SGC Building, 13737 S.E. 26th St. Bellevue, WA. 98005 USA

15.0 Marine Installation

Installation of the SG-2000 in the marine environment requires considerable care

in order to achieve highly reliable operation because while the SG-2000 is a very

reliable radio, the marine environment brings with it unique problems. These

fall into three general areas: Installation of the radio, obtaining a proper ground

system, and use of a suitable antenna.

15.1 Marine Radio Mounting

The most common configuration of the SG-2000 in the marine environment is use

of a standard mounting tray (SGC Part Number 52-46) and the remote head kit

(SGC Part Number 04-12). With the control head detached from the body of the

radio, the operating position may be made much more compact.

SGC does not presently provide a flush mounting kit for the SG-2000. Instead,

we recommend the use of the remote head kit's gimbal mount. This allows for

the control head angle to be changed to prevent glare off the display screen and

allows individual operators to adjust the unit for the most comfortable operation.

In the event that you need to disconnect one end of the control head wiring in

order to route cable, please disconnect the female plug end. Disassembly of the

control head to remove wires from the control head is not recommended for

inexperienced installers. If you do need to remove the plug to route cable,

carefully note the connections of each wire. When the wiring is reassembled,

care must be exercised to prevent wires from touching.

Power wiring to the SG-2000 should be through its own breaker. This breaker

should be 30 amps and the routing of the wire should be as direct as possible.

The minimum wire size which should be used is number 6 (AWG). Wires should

be both crimped and soldered to connectors prior to being attached to the power

barrier strip. Connections at the D.C. panel should be securely made.

15.2 Marine Ground Systems

“Bonding,” as it is called in marine circles, is the process of tying all vessel metal

into a single electrical point. The reason for bonding is that for an HF radio

antenna to radiate properly, a large counterpoise of more than 100 square feet of

metal must be present under the antenna.

This is not difficult provided you are willing to invest a certain amount of time.

The recommended bonding material is copper foil. Available in several widths,

the foil should be routed to keep all leads direct.
