1.6 Mechanical Design
The SMARTUNER is supplied in a weatherproof case with two mounting brackets. RF
and DC power are supplied to the unit through the same cable. This special cable
consists of a 50-ohm coaxial cable and four conductors. The four conductor wires are
for the ground, the positive power lead, the optional SmartLock control, and optional
LED indicator.
The SMARTUNER antenna coupler’s weatherproof case is designed to withstand the
environmental conditions encountered aboard ship when mounted on the
weatherdecks. 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 gasket that seals the unit is relocated
properly to maintain watertight integrity of the unit.
Although the SMARTUNER is built very solidly, it is good installation practice to
provide additional protection from the elements. SGC makes the following
recommendations:
