Digital Radome Scanner - User Guide
Planning the installation
Mount the scanner as high as possible above the waterline for better long
range performance, but make sure it:
• is above head height.
• is easily accessible.
• is as near to the boat’s centerline as possible.
• is on a rigid and stable platform.
• is clear of large objects such as the flybridge, large engine stacks,
searchlights, horns or masts.
• is clear of heat and fumes.
• is at least 1 m away from a magnetic compass or other equipment
antenna.
Don’t put the scanner so high, that it is affected by the pitching and rolling
of the boat.
Mount the scanner so that the array rotates parallel to the waterline.
The radar beam is approximately 25
o
wide in the vertical direction, giving
good target detection when your boat pitches and rolls.
Planing hull and some displacement hull boats adopt a higher bow angle
when the boat is at cruising speed, giving poor target detection. It may be
necessary to lower the radar beam back towards the parallel, by shimming
the rear of the radar, so that the beam points slightly down when the boat
is at rest. Refer to the diagram on page 14 for more information.
