The SG-235 is supplied in a weather proof case with two mounting brackets. RF
and DC power are supplied to the unit through the same cable. This special
cable comprises a 50-ohm coaxial cable and 12 conductors. The 12 conductor
wires include the ground, the positive power lead, the optional SmartLock con-
trol, and the optional LED indicator.
The SG-235 antenna couplerÕs weatherproof case will withstand the environ-
mental conditions encountered aboard ship when mounted on a weatherdeck.
The internal construction is designed to withstand the shock and vibration of
marine service. Corrosion-resistant hardware and passive alloys are employed
throughout.
We do not recommend opening the Smartuner case unless it is necessary. For
99% of installations, the factory settings for jumpers will be correct. Should
you have occasion to open the case, use care to ensure the sealing gasket is
placed properly to maintain watertight integrity of the unit.
Although the Smartuner is solidly built, good installation practice calls for
additional protection from the elements.

The Smartuner should be located inside the house or under the aft lazaret on a
sailboat. On power boats, the coupler may be mounted outside, but additional

CAUTION:
Dangerous high voltages exist inside the Smartuner when it is oper-
ated with an HF transmitter. High RF voltages in excess of 10 kv
may be expected in normal operation of this unit. In addition to
shock hazard, these RF voltages may produce burns which are very
painful if you come in contact with exposed components. Therefore,
DO NOT operate without the cover secured in place unless you are a
well experienced radio technician or engineer.
As a matter of good installation and engineering practice, exposed
metal antenna elements should be located in such a manner as to
prevent accidental contact with people (especially young children),
pets, and small animals.
