Mounting Procedure

Note 1: The bird-repellent fixtures (optional supply) can be attached to the antenna cover to
vent birds from landing on the cover. If it is more convenient to attach the bird-repellent fixtures
before securing the antenna unit to the mounting location, do step 6 below before fixing the an-
tenna unit.
Note 2: According to the installation location, connecting the antenna pig tale connector to the
NMEA2000 bus or a cable from an optional unit in advance is easy to fix to the location. Connect
a cable with reference to step 5 beforehand. Then, waterproof the connection.
1. As shown in the figure below, weld a platform (local supply) for which to mount the satellite
compass. The thickness of the platform should be 5 mm to 15 mm.
