Mounting Considerations

In addition to the considerations described in this section, keep the length of the SC-33 cable in
mind when selecting a mounting location.
General considerations
Mount the SC-33 above radar mast
As shown in the figure below, mount the SC-33 above a radar mast. This provides an unobstruct-
ed path between the SC-33 and the satellite, regardless of vessel heading. Follow the procedure
on the next page to choose an installation site.
If SC-33 cannot be installed above radar mast
If absolutely impossible to do otherwise, the SC-33 may be installed below a radar mast. However,
certain guidelines must be followed to prevent the shading and multipath problems which occur
as shown in the figure below. Follow the procedure on the next page to choose an installation site.
