INSTALLATION CONSIDERATIONS
3.1
Mounting
The amplifier can be:
*
used free standing;
*
mounted in a flight case;
*
mounted on the roof of a vehicle;
*
mounted to an antenna system.
The amplifier has a flange which should be used to mount the amplifier solidly to the
chosen platform. Six M5 clearance mounting slots (three each side) are provided, to
allow fixing from above. Suitable load spreading washers should be used to protect
the amplifier from damage during the mounting process. Suitable locking nuts and/
or locking washers should be used to prevent the amplifier from working loose under
vibration and shock conditions that each installation may impose. This is especially
important for mobile applications.
The amplifier should be positioned so as to avoid the direct entry of rain water into
the ventilation slots. The amplifier is provided as standard with an air inlet cowl, the
normal orientation of which is pointing towards the base of the unit, to avoid the
direct entry of driving rain. When used with this arrangement, the unit should not be
mounted closer than 42 mm from any flat surface, to avoid choking of the forced air
cooling system (see figure 1).
