2.1Mounting Considerations

2.1.1Antenna 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.
