Tips for Successful Antenna Unit Placement and Mounting
•
The mounting surface should be essentially flat,
free of vibration and flexing, and strong enough to
carry the complete assembly (30 lbs/13.6 kg).
•
The antenna unit need not be located exactly on
the vessel’s fore-and-aft axis, but its centerline
reference MUST be parallel to it.
•
Be sure to account for the radome height and the
base dimensions, illustrated in Figure 2-1.
Antenna Unit Mounting Procedure
1. Using the base dimensions presented in Figure 2-1
on the following page or the template provided in
Appendix B,
lay out the four mounting bolt holes.
Check the layout of the baseplate to ensure that it
is parallel with the vessel’s fore/aft axis.

Antenna Unit Kitpack Contents
Always lift the antenna unit by the
gray baseplate structure, not the
radome. Also be careful not to
strike the exposed connectors
extending from the bottom of the
baseplate or allow them to carry
the weight of the antenna unit.
