Centerline
The scanner unit should be mounted on the centerline of your boat in a location that has an unobstructed
view forward and is as clear as possible the rest of the way around the unit.
Height
Choose a location as high as practical to improve maximum range, but not so high as to be adversely affected
by the vessel’s pitching and rolling. Also, keep in mind that minimum range objects may be overlooked if
mounted too high.
Unobstructed View
Position the Radar scanner forward of large structures and exhaust stacks. Contamination from engine
exhaust on the scanner housing reduces radar performance.
• Antennas for GPS, radio communication, or other equipment should not be located in the radar
beam.
• Use non-metallic extension poles to move the active area of antennas above the radar beam.
Blind Spots, Shadow Areas, and False Echoes: Large structures or stacks may cause blind spots and/or
false echoes.
• Wet sails may also cause shadow areas, so Radar performance may be reduced in the rain.
• If you mount the Radar scanner on a mast, echoes from other targets may be reflected from the mast.
• It is particularly important to avoid shadow areas near the bow.
• In shadow areas beyond the obstruction, there will be a reduction of the beam intensity. There may
be a blind sector if the beam intensity is not sufficient to obtain an echo from an object. This may
occur even at close range. For this reason, the angular width and relative bearing of any shadow area
must be determined at installation.
• Identifying shadow areas and/or false echoes on the control head: For example, adjust the
settings on your control head to view sea clutter. Dark sectors on the Radar display indicate possible
shadowed areas. See your control head operations manual for more information.
