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.
