Garmin GMR Fantom 5x radar pedestal, upper part

For optimal performance and safety, consider the following points when selecting the mounting location:

The radar must be mounted out of reach of people, with the vertical beam width above head height. It must be installed high above the vessel's keel line, with minimal obstruction to the radar beam. The mounting surface must be flat, parallel to the vessel's waterline, and sufficiently robust to support the radar's weight. The radar must be mounted where power, ground, and network connections can be made. Avoid mounting the radar near heat sources (exhausts, lights) or at the same height as horizontal spreaders or mast cross-trees. Other electronic equipment and cables must be more than 2 meters (6.5 feet) from the radar beam path. GPS antennas must be either above or below the radar beam path. Maintain a distance of at least 1 meter (40 inches) from any transmitting equipment and cables carrying radio signals (VHF). Maintain a distance of at least 2 meters (6.5 feet) from SSB radios.

For the radar pedestal installation, you will need the following tools:

A Phillips screwdriver size #2A 6 mm Allen wrenchA drillA 15 mm (19/32 in) drill bitA 32 mm (1 1/4 in) drill bit (optional, for cable routing)A 17 mm (21/32 in) wrench and a torque wrench12 AWG (3.31 mm²) bare copper wire for grounding the radar housing and voltage converter (if applicable)Marine sealant

Yes, the radar (and the voltage converter, if applicable) must be connected to a dedicated water ground. A 3.31 mm² (12 AWG) copper wire (not included) is required. This wire must be routed to a water ground point and connected to the ground connector on the pedestal. After connection, the ground screw and crimp connector must be coated with marine sealant.

Radar transmits electromagnetic energy. To avoid injury, ensure all persons are clear of the radar beam path before transmitting.Never look directly at the antenna up close while the radar is transmitting, as the eyes are the most sensitive part of the body to electromagnetic energy.Do not remove the built-in fuse from the power cable. The correct fuse must be in place to prevent fire or overheating risks.Installation by a qualified marine installer is recommended for optimal performance and to avoid damaging the device or the vessel.Never open the device yourself, as it contains no user-serviceable parts and must only be opened by a Garmin authorized service technician.Use the device solely as a navigation aid.Always wear safety glasses, hearing protection, and a dust mask when drilling, cutting, or sanding.

No, it is strongly advised against opening the GMR Fantom 5x radar pedestal yourself. The unit contains no user-serviceable parts and must only be opened by a Garmin-authorized service technician. Any damage resulting from opening the unit by someone other than a Garmin-authorized service technician will not be covered by the Garmin warranty. Additionally, the radar contains high voltages and generates non-ionizing radiation, which poses risks of serious injury or death.

To mount the antenna on the pedestal:

Remove the protective cover from the waveguide located on top of the pedestal. Align the pedestal’s waveguide with the socket under the antenna, then slide the antenna onto the pedestal. Secure the antenna to the pedestal by tightening the captive hex bolts located under the antenna arm. Tighten the hex bolts to 7.9 N·m (6 lbf·ft) to firmly secure the antenna without damaging it or the mounting hardware.
