3.1 Antenna Unit Installation
Mounting considerations
When choosing a mounting location for the antenna unit, keep in mind the following points:
•Install the antenna unit on the hardtop, radar arch or on a mast on an appropriate platform. (For sailboats, a mounting bracket is optionally available.) It should be placed where there is a good
•In order to minimize the chance of picking up electrical interference, avoid where possible routing the antenna cable near other electrical equipment onboard. Also, avoid running the cable in parallel with power cables.
•Separate the antenna unit from a magnetic compass by the distances noted below to prevent interference to the magnetic compass:
Standard compass: 1.25 m
Steering compass: 0.85 m
Mounting on a platform
1.Remove mounting hardware at the bottom of the antenna unit; four each of hex bolts (M10X20), spring washers and flat washers. Save mounting hardware to use it to fix the antenna unit to the mounting platform later on.

2.Construct a wood, steel or aluminum platform on which to fix the antenna. (The thickness of the platform depends on the hex bolts to be used to fix the antenna to the platform. See the illustration on the next page for thickness.) Next, position the antenna unit so the cable gland faces toward boat’s stern.
Note 1: If corrosive material is used for the platform, take appropriate anticorrosive measures to prevent corrosion.
Note 2: When drilling holes in the platform, be sure they are parallel with the fore and aft line.
