8 Radome Scanners - Users 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 displace-
ment hull boats
adopt a higher
bow angle when
the boat is at
cruising speed.,
giving poor
target detection.
It may be neces-
sary 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.
