Minimum distance from other antennas
HF antennas, communication/navigation antennas:
The antenna should be at least 5 meters from a HF antenna. VHF, satellite navigation
antenna and other communication antennas should be at least 4 meters away.
Radar:
The antenna should be at least 5 meters away to protect the low noise amplifier in the radar
antenna. However, if this distance cannot be secured be sure the antenna is not within the
radar beam.
More than 5 m
If installed within 5 m of

Locating the antenna unit too close to a compass can affect compass performance. The
compass safe distance is 0.75 meters, steering compass, 0.45 meters, standard compass.

Other important mounting guidelines are
•
Locate the antenna unit away from exhaust stacks (foreign material on the radome can
interfere with reception and transmission).
•
Keep the unit away from heat sources.
•
Locate the unit away from places where fuels and chemical solvents are stored.
•
Keep in mind the length of the cable from the communication unit is maximum 100
meters.
