1.2 Antenna Unit for MODEL1835
How to select the location for the antenna unit
When you select an installation location for the antenna unit, remember the following points.
Install the antenna unit on a solid location, for example radar arch or on a mast on a platform.
(For sailboats, a mounting bracket is optionally available.) You must put the antenna unit where
there is a good complete view. Make sure that no part of the superstructure is within the scan-
ning beam. Any obstruction causes shadow sectors. For example, a mast with a diameter
smaller than the horizontal beamwidth causes only a small blind sector. A horizontal spreader
or crosstrees in the same horizontal plane creates a large obstruction. Install the antenna unit
above a horizontal spreader or crosstrees.
Normal position of the antenna unit on the sailboat and powerboat
To reduce the electrical interference, do not run the antenna cable near other electrical equipment.
Also do not run the cable in parallel to power cables.
Make sure that you follow the compass safe distance shown on page i to prevent the interference
to a magnetic compass.
