Antenna mounting guidelines
The MX521B antenna housing is weather-resistant and must be
located outside where it will have a good view of the sky around it.
Use a standard 1”-14 TPI bracket or tube for mounting.
•
Install the antenna where it has a clear view of the sky around it.
•
Locate the antenna for easy access and maintenance.
•
Stay away from high-power energy sources such as radar, SSB,
INMARSAT and other transmitting radio antennas by 5 meters or
more.
•
Locate the antenna at least 10 meters away from, and out of the
transmitting beam of radar, INMARSAT and other high-power
transmitters.
•
Mount the antenna low to avoid excessive position and speed errors
while underway.
•
Mount the antenna as far away as possible from large metal
structures.
•
Mount the antenna at least 1 meter away from the compass and
other GPS antennas.

Note:
If you are not sure if the chosen location is appropriate, you
can mount the antenna temporarily and check signal reception from
your CDU. Monitor the operation of the antenna while you turn on
other on-board electronic equipment. Move the antenna around
until the antenna operates satisfactorily then mount it permanently.

Note:
Powerful Xenon-Arc search lights emit electromagnetic
radiation, which may interfere with communication and navigation
systems on board. The preferred location for the GPS antenna is at
least 3 meters above the light.
