10kW and 25kW Installation Manual
When you’re deciding on the location, please consider:
•
To avoid the scanner coming in contact with other installed objects while it is rotating, ensure
that there is at least 200 millimeters between the swing circle (turning radius) and the other
installed objects. Observe the following swing circle when determining mounting location:
Scanner antenna
diameter of swing circle
4 foot
1,320 mm
6 foot
1,910 mm
7 foot
2270mm
•
The length of the interconnection cable supplied with your radar is usually suffi
cient. If you
think you’ll need a longer cable, consult your dealer before installation, because a longer
cable may reduce the performance of the radar.
•
If the roof of the wheelhouse is the highest existing location, consider installing a radar
mast or a pedestal on which you can mount the scanner. You may also need to construct a
working platform for your own safety during installation and servicing work.
•
If you mount the scanner on a pedestal or base, ensure that rain and sea spray can drain away
from it rapidly.
•
If you locate the scanner on the mast, position it on the forward side so that there is a clear
view to the front of the vessel.
•
The scanner is usually installed parallel to the line of the keel.
•
Ensure that the location site provides the scanner with a clear view of the front of the vessel.
DON’T DO THIS!
•
DON’T install the scanner too high up, where its weight will alter the stability of the vessel and
cause degrade the radar picture over short ranges.
•
DON’T install the scanner close to lamps or exhaust outlets. The heat emissions may cause
the equipment to break down. Soot and smoke will degrade the performance of the radar.
•
DON’T install the scanner close to the antennas of other equipment such as direction fi nders,
VHF antennas, GPS equipment etc, as it may cause interference.
•
DON’T install the scanner where a large obstruction (such as an exhaust stack) is at the same
level as the beam. The obstruction is likely to generate false echoes and/or shadow zones.
•
DON’T install the scanner where it will be subjected to strong vibrations (such as a derrick
post) because these vibrations will degrade the performance of the radar.
•
DON’T install a scanner close to halyards or fl ags because the wind or boat movement could
cause entanglement with the rotating antenna.
!
Warning:
DON’T install the scanner inside of the recommended compass safe
distances of any navigation instruments such as the magnetic compass and the
chronometer. The compass safe distances are as follows:
10 kW radar
STD 2.4 m (7.9 ft) / STEER 1.8 m (6 ft)
25 kW radar
STD 2.4 m (7.9 ft) / STEER 1.8 m (6 ft)
Power boat installations
Normally, you should install the scanner horizontally, to produce an equal sweep around the
boat:
