Radar scanner mounting angle
Ensure the Radar scanner rotates parallel to the water line.
The Radar beam from the Radar scanner is approximately 20° wide in the vertical direction, to give
good target detection even when your vessel pitches and rolls.
Planing hull vessels, and some displacement hull vessels, adopt a higher bow angle when the vessel
is at cruising speed. This may raise the Radar’s main radiation angle, and can cause poor detection
of nearby targets. It may be necessary to compensate for the bow rise to ensure optimum target
detection. This can be achieved by fitting a wedge or washers between the mounting platform and
the base of the Radar scanner, so that the Radar beam remains parallel to the water line when the
vessel's bow rises at cruising speed.

Multiple Radar scanners — location requirements
Important location considerations when installing multiple radar scanners on the same vessel.
• Scanners should be mounted above each other, vertically separated by at least 0.5 m (1.6 ft). This
applies to all installation locations on the vessel.
• Multiple scanners should be mounted in a way that minimizes interference between the vertical
beamwidths of the 2 scanners.
• In all cases, you should aim to achieve as much physical separation as possible, to minimize
any potential interference.
