Mounting Considerations

In addition to the considerations described in this section, keep the length of the s atellite compass
cable in mind when selecting a mounting location.
General considerations
Mount the satellite compass above radar mast
As shown in the figure below, mount the SC-33 satellite compass above a radar mast. This pro-
vides an unobstructed path between the satellite compass and the satellite, regardless of vessel
heading. Follow the procedure on the next page to choose an installation site.

If satellite compass cannot be installed above radar mast
If absolutely impossible to do otherwise, the satellite compass may be installed below a radar
mast. However, certain guidelines must be followed to prevent the shading and multipath prob-
lems which occur as shown in the figure below. Follow the procedure on the next page to choose
an installation site.
