Mounting Considerations

To complete the installation, you need the appropriate fasteners, tools, and mounts. These items are available

at most marine dealers.

When selecting a mounting location, observe these considerations.

•

You must mount the radar out of range of people, with the vertical beam width above head height. To avoid

exposure to harmful radio frequency (RF) levels, you must not mount the radar closer to people than the

minimum safe distance value listed in the product specifications.

• You should mount the radar high above the ship's keel line with minimal blockage between the vessel and

the radar beam. Obstructions may cause blind and shadow sectors, or generate false echoes. The higher the

installation position, the farther the radome can detect targets.

• If you are mounting the radar on a cabin roof, you may need to install a raiser so the roof does not interfere

with the radar signal

(Roof Mounting Considerations,

• 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 is listed in the product specifications.

• The radar must be mounted in a location where it can be connected to power and the Garmin network

and Connection Considerations,

• Most radar beams spread vertically 12.5 degrees above

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. Use shims if necessary.

• The radome has two mounting options when installed on a standard marine mount. One mounting option is

closer to the center of the radome

further away from the mast.
