About the VHF antenna
A key element in the performance of any communication sys-
tem is the antenna. The VHF AIS/radio antennas should be
mounted in a location that has a clear, unobstructed view in
all directions and as far away from interference as possible,
for the best reception and transmission. When selecting a
mounting location, follow the guidelines below.
- Mount the VHF AIS/radio antennas at least 3 m (9.85 ft.)
away from each other.
- Mount the VHF AIS/radio antennas as high as possible.
- Be sure the location is out of the radar beam.
- Be sure the location will not be shaded by a random antenna
or mast.
