Mounting Considerations
When selecting a mounting location, observe these considerations.
•
WARNING
The radar must be mounted out of range of people, with the vertical beam width above head height. To avoid
exposure to harmful radio frequency (RF) levels, the radar must not be mounted closer to people than the
minimum safe distance value listed in the product specifications.
• The radar should be mounted high above the ship’s keel line with minimal blockage of the radar beam.
Obstructions may cause blind and shadow sectors or generate false echoes. The higher the installation
position, the farther the radar can detect targets.
• The radar should be mounted on a flat surface or a platform that is parallel to the vessel's water line and is
sturdy enough to support the radar's weight. The weight for each model and antenna is listed in the product
specifications.
• The radar must be mounted in a location where it can be connected to power, water ground, and network.
• The radar beam spreads vertically 11.5°above and 11.5°below the radar's radiating element. On vessels
with higher bow angles at cruise speed, the installation angle can be lowered to point the beam slightly
downward to the waterline while at rest. Shims can be used if necessary.
• The radar should be mounted away from heat sources, such as smoke stacks and lights.
• The radar should be mounted at a different level than horizontal spreaders and mast crosstrees.
• To avoid interference with a magnetic compass, the radar should not be mounted closer to a compass than
the compass-safe distance value listed in the product specifications.
• Other electronics and cables should be mounted more than 2m (6.5ft.) from the radar beam path.
• GPS antennas should be either above or below the radar beam path.
• The radar should be mounted at least 1m (40in.) from any transmitting equipment.
• The radar should be mounted at least 1m (40in.) away from cables carrying radio signals such as VHF
radios, cables, and antennas.
• The radar should be mounted at least 2m (6.5ft.) away from Single Side Band (SSB) radios.
