Raymarine Radar Scanner Setting the radiation plane

10 Pathfinder Radar Scanners

Setting the radiation plane

The scanner unit should be mounted so that the array rotates parallel

to the waterline. The radar beam is approximately 25° wide in the

vertical direction, providing good target detection during the vessel’s

pitching and rolling.

Planing hull vessels, and some displacement hull vessels, adopt a

higher bow angle when the vessel is at its cruising speed. In many

cases this substantially alters and raises the radar’s main radiation

plane, and can cause poor detection of nearby targets. It may be

helpful to lower the radar beam back towards the parallel, by

shimming the rear of the radar, so t hat the bea m points sl ightly

downwards with respect to the waterline when the vessel is at rest.

The shims may be made from aluminium plate wedges, simple flat

washers, or an angled wooden block. For thick shims, you may need

longer securing bolts than the M8x40 bolts supplied with the radome

scanner, or the M10 studding supplied with the open array scanners.
