Raymarine Radar Scanner - Manual (Page 17)

Chapter 1: Overview 9
For open array scanners you should also consider the following
points:
• Mounting Platform: The platform must be mechanically secure
and capable of supporting the mass and inertia of the open array
scanner. The complete unit weighs: 48" scanner - 30 kg (66.2 lb);
72" scanner - 33.4 kg (73.7 lb).
• The site must be clear of ropes and moving rigging.
• Sufficient clearance must be allowed to fully open the open array
pedestal for maintenance.
Mounting surface: sailboats
The scanner unit can be installed on a mast platform, an arch, or a
bridge structure. Make sure that the platform surface is flat and the
scanner unit drain hole (radome scanners) is not obstructed.
Raytheon recommends that radome scanner units are best suited for
sailboat operation as open array systems are more difficult to protect
from ropes and sails.
For sailboat installations, Raytheon offers a universal mast mount kit
for each radome scanner type. This optional mount is used to fit a
radome scanner to a flat surface on a mast with a minimum diameter
of 60 mm (2½ in). When using the mast mount kit, appropriate
hardware should be used for the style and structure of the mast aboard
the vessel. Typically, the scanner will be mounted near the first set of
mast spreaders. If there is any doubt concerning the appropriate type
of hardware, consult your boat dealer or representative for their
recommendations.
Depending on the type of sailboat, a radar scanner guard should be
installed if the sails could touch the scanner or platform. Without a
proper radar guard the mounting platform and the radar scanner could
be severely damaged.
Mounting surface: power boats
On many small vessels the scanner unit can be installed on a mast
platform, an arch, or a bridge structure, but take care to follow the
scanner site guidelines, particularly regarding height. If necessary,
construct a radar mounting platform to obtain a sufficiently high
mounting position. Make sure that the platform surface is flat and the
scanner unit drain hole (radome scanners) is not obstructed. Ensure
the platform is strong enough to support the maximum shock loads
likely to occur.
