1.0 Supplied Items
SG-239 Coupler
Manual
Quick-Start Card
2.0 Mechanical Design
The SG-239 is supplied in an aluminum case with mounting holes.
RF and DC power is supplied to the unit through terminals accessi-
ble on the outside of the case. The internal construction is designed
to withstand the shock and vibration of marine service. Corrosion-
resistant hardware and passive alloys are employed throughout. For
99% of installations, the factory settings for jumpers will be correct.
The coupler must be installed in an area not directly exposed to the
sunshine or rain. Although the Smartuner is built very solidly, it is
good installation practice to provide additional protection from the
elements. SGC makes the following recommendations:
2.1 Marine Mounting
The Smartuner should be located inside the house or under the aft
lazaret on a sailboat installed in a waterproof case. The preferred in-
stallation if vertical is with the RF terminals pointing upward. The
antenna connects to the screws on the top. The SG-239 may be
mounted in any position including inverted without any
degradation of performance. To waterproof a SG-
239, place the unit in a sealable food con-
tainer, (1.7 liter - 7 cup standard size)
2.2 Desert and High Temperature
Installations
The Smartuner may be used in very hot cli-
mates on a continuous basis if some additional
protection from direct sunlight is provided and if
coupler is installed in a waterproof case. Tempera-
tures inside a vehicle may exceed 212°F (100°C). It is
desirable to keep the coupler in the shade if possible.
