1.6.1 Marine Mounting
The SMARTUNER should be located inside the house or under the aft lazaret on a
sailboat. On powerboats, the coupler may be mounted outside, but an addition
protective housing is recommended. The preferred installation if vertical is with the
standoff insulator pointing upward.
A stuffing gland for the RF and DC cables is provided on the lower edge of the weather
housing, along with a 1/4-20 stainless steel ground stud. The antenna connects to the
ceramic insulator on the top of the weather housing.
The SMARTUNER may be mounted in any position including inverted without any
degradation of performance. If the coupler is to be exposed to long periods of high
vibration, such as aboard helicopters or tug boats, installation of the optional shock
mounting is recommended.
1.6.2 Desert and High Temperature Installations
The SMARTUNER may be used in very hot climates on a continuous basis if some
additional protection from direct sunlight is provided. The best protection for a mobile
installation is provided by the QMS (Quick Mounting System) that keeps the antenna
coupler outside of a vehicle. Temperatures inside a vehicle may exceed 212°F (100°C). If
a QMS is not used, it is desirable to keep the coupler in the shade if possible. Please
refer to the diagram in the following section.
1.6.3 Extremely Cold Temperature Installations
Your SMARTUNER will operate down to specified temperatures. We recommend
placing the SMARTUNER under some kind of housing other than the case to prevent
heavy build up of ice. If you are mounting on a tower in a hot or cold climate, a plastic
wastebasket (such as those made by Rubbermaid™) makes an excellent weather cover
and costs only a few dollars.
