Avoid interference
The Antenna Unit should be separated as far as possible from other
communication and navigation antennas onboard such as Radar,
Satellite, HF/VHF/UHF, GPS antennas etc.. Preferably by 5 metres.
The Antenna Unit should be installed so that severe vibration and
shock are avoided. If installed on top of a pipe or signal/radar mast,
the mast must be supported by stays.
The equipment is supplied with gasket and a flange for mounting of
the Antenna Unit on top of a 42.4 mm outer diameter pipe.
Other installation bracket is optional.
Coax cable
A 12 metre coaxial cable type RG-223 (QRPM 911084-12000) is
supplied as standard.
For greater lengths, see
The coax cable should be secured by laying the cable in a tube and/
or by fastening the cable to avoid damage.
Telephone Unit (TPU) and Power Supply (PS)
The PS is provided with holes for mounting on desktop or bulkhead
with the TPU snapped on top of PS by fastening clips.
The TPU may be installed separately by using 3 metre extension
cables between PS and TPU:
• coaxial cable, QRPM 911087-3000
• DC cable, QRPM 911079-3000
Source of energy
The equipment operates from 10 to 32 Volts DC from any 12V or 24V
battery.
Power supply for operation from 230 VAC may be supplied as an
option, QBMJ 101002.
