Mounting considerations
When selecting a mounting location, keep in mind the following points.
Select a location which provides adequate ventilation.
The location should be clean and dry.
The mounting location must be able to support the weight of the unit (PR-300:14.5 kg,
PR-850A: 35 kg) under the continued conditions of vibration normally encountered aboard
the vessel.
A magnetic compass will be affected if the power supply unit is placed too close to it.
Observe the following compass safe distances to prevent disturbance to the magnetic
compass shown on page ii.
Mounting
Refer to the outline drawings at the back of this manual.
1.6.2
Preamp unit FAX-5
The body of preamp unit can be mounted two ways:
1. The bottom of the preamp unit is designed to accept a threaded extension mast of 1 inch
diameter. The pitch of the thread should be 14 threads per inch. To prevent undue flexing of
the mast in heavy winds, the mast should not be longer than 5 feet (1.5 m).
2. The side of the preamp unit has a molded channel so that it may be mounted directly to a
stub mast with two stainless steel hose clamps. Hose clamps must be arranged locally.
Screw the 2.6 m whip antenna (option) tightly onto the preamp unit and waterproof the junction
and other exposed metallic parts with sealing compound (silicone rubber, putty, etc.)
Note that a wire antenna of 2 to 3 meters length may be used instead of the whip antenna.
Note: The preamp unit requires 12 VDC power. See paragraph 3.5 for how to provide power to
the preamp unit.
