unit 
General 
• 
Keep the length of the antenna cable in mind when selecting a mounting 
location.  
 
Installing the antenna above superstructures 
• 
The antenna must be mounted above all other structures on the vessel to 
obtain an unobstructed view of the satellites regardless of vessel heading. 
Failure to do so will cause shadows and multipath reflection problems.

Example of antenna installed above all superstructures 
 
Installing the antenna below superstructures 
If it is not possible to mount the 
antenna above all superstructures on 
the vessel, as shown in the illustration 
above, shading and multipath 
problems may occur on at least one 
heading, and possibly more. To 
possibly avoid those problems, 
observe the guidelines in this section. 
 
NOTICE
If the antenna is installed below any 
superstructure, the installation must
be done over a two-day period, following
the procedure in the service manual.
At least 12 hours are required to capture
tracking data to measure multipath indexes
and locate areas of shading.
