1.1Antenna Unit Installation

Mounting considerations

When selecting 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 all-round view with, as far as possible, no part of the ship’s superstructure or rigging intercepting the scanning beam. Any obstruction will cause shadow and blind sectors. A mast, for instance, with a diameter considerably less than the width of the antenna unit, will cause only a small blind sector. However, a horizontal spreader or crosstrees in the same horizontal plane would be a much more serious obstruction; place the antenna unit well above or below it.

•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.

•The compass safe distance of 1.25 meters (standard compass) and 0.95 meters (steering compass) should be observed to prevent deviation of the magnetic compass.

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.Unfasten three screws to remove the cover.

3.Construct a platform (wood, steel, or aluminum) of 5–10 mm in thickness whose dimensions are as shown in Figure 4. Fasten the platform to the mounting location. Next, position the base so the cable entrance faces the stern direction and the vent tube is extending downward through the hole for the vent tube.

Note: When drilling holes in the platform, be sure they are parallel with the fore and aft line.
