Mounting Considerations
When selecting a mounting location, observe these considerations.
• It is highly recommended that the device is mounted out of range of people, with the vertical beam width
above head height. To avoid exposure to harmful radio frequency (RF) levels, the device should not be
mounted closer to people than the maximum safe distance value listed in the product specifications.
• The device 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 device 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 device's weight. The weight for each model and antenna is listed in the product
specifications.
• The device must be mounted in a location where it can be connected to power, water ground, and the Garmin
Marine Network
(Wiring and Connection Considerations,
• The radar beam spreads vertically 11.5° above and 11.5° below
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 device should be mounted away from heat sources, such as smoke stacks and lights.
• The device should be mounted at a different level than horizontal spreaders and mast crosstrees.
• To avoid interference with a magnetic compass, the device 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 device should be mounted at least 1 m (40 in.) from any transmitting equipment.
• The device should be mounted at least 1 m (40 in.) away from cables carrying radio signals such as VHF
radios, cables, and antennas.
• The device should be mounted at least 2 m (6.5 ft.) away from Single Side Band (SSB) radios.
