Choose the scanner location
The radar's ability to detect targets greatly depends on the position of its scanner. The ideal
location for the scanner is high above the vessel's keel line where there are no obstacles.
A higher installation position increases the radar ranging distance, but it also increases the
minimum range around the vessel where targets cannot be detected.
When you're deciding on the location, consider the following:
• The length of the interconnection cable supplied with your radar is usually sufficient. If you
think you'll need a longer cable, consult your dealer before installation. Optional cable
lengths are 10 m (33 ft), 20 m (65.5 ft) and 30 m (98 ft).
• If you mount the scanner on a pedestal or base, ensure that rain and sea spray can drain
away rapidly, and the breather hole in the base can operate .
• The scanner is usually installed parallel to the line of the keel.
DON'T DO THIS!
• DON'T install the scanner too high up, which may cause degradation of the radar picture over
short ranges.
• DON'T install the scanner close to lamps or exhaust outlets. The heat emissions may
damage the dome. 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 finders,
VHF antennas, GPS equipment 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, because 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 because these
vibrations could degrade the performance of the radar.
• DON’T install the scanner such that boat electronics with switch mode power supplies (such
as fish-finders and chart plotters) are in the beam of the antenna.
Minimum distance to install near the ships
compass is 0.7 m (3.3 ft).
It is recommended not to install the scanner on the
same beam plane as a conventional pulse radar. A
pulse radar must be set to STBY or OFF when the
BR24 is being operated.
If possible ensure that the location site
provides the scanner with a clear view all
round the vessel.
Installations on power boats that have a
steep planing angle, it is recommended to tilt
the scanner angle down at the front. (Beam
angle is 12.5° either side of center).
