Mounting considerations

The water-jetsproof construction of the antenna coupler permits installation either indoors or
outdoors. When selecting a location, keep in mind the following points.
Outdoor installation
•
Select a location not exposed to salt water spray. Salt water on the antenna insulator may
cause unstable operation of the coupler and in the worst case prevent transmission.
•
All wires from the coupler to the antenna radiate radio energy. They should be routed away
from any grounded conductors such as mast shrouds, or fittings.
•
For optimum radio energy, locate the coupler as near to the ground as possible.
•
The length of the vertical portion of the antenna should be as long as possible.
•
Leave enough space around the sides of the unit to permit maintenance and checking.
•
Total antenna length should be 7 to 30 meters.
