GMR Fantom 12x radar pedestal, upper assembly

The GMR Fantom 12x radar pedestal upper assembly is the main component of the Garmin GMR Fantom 12x open-array radar systems. It is specifically designed to house the radar’s essential electronics and to support the antenna. This part is critical for ensuring the proper operation, stability, and structural integrity of the entire radar system aboard your vessel. It can be used as a replacement part for existing GMR Fantom 12x installations.

To ensure optimal performance and safety, the GMR Fantom 12x radar pedestal must be installed while respecting several key considerations:

It must be positioned out of reach of people, with the vertical beam above head height. The minimum safe distance from people must be respected (this value is specified in the product specifications). The radar must be mounted high relative to the vessel’s keel line, with minimal obstructions to the radar beam. The mounting surface must be flat and sufficiently robust to support the radar’s weight. The pedestal must be mounted at a safe distance from heat sources, spreaders, and mast cross-ties. It must be kept at a safe distance from a magnetic compass, as specified in the product specifications. Other electronic equipment and cables must be more than 2 meters away from the radar beam path. GPS antennas must be either above or below the radar beam path.

Connecting the GMR Fantom 12x radar pedestal to the power supply can be done in two main ways, depending on whether your model is supplied with a voltage converter or not:

With a voltage converter: If your model is supplied with a converter, you must install it. The converter requires an input voltage of 10 to 32 V DC and must be installed as close as possible to the power source. The radar's power cable includes a 15 A fuse that must not be removed. A 30 A fuse is also included to connect the converter to the boat's battery.

Directly to the battery (without converter): Some radar models do not require a voltage converter and can be connected directly to the boat's battery (10 to 32 V DC). In this case, the 15 A inline fuse holder on the radar's power cable must not be removed.

It is recommended to connect the power cable directly to the battery. Any cable extension must use a wire gauge appropriate for the length to avoid radar malfunction due to insufficient power supply.

Ensure all connections are properly insulated and protected from moisture.

Yes, the GMR Fantom 12x radar pedestal, as well as the voltage converter (if applicable), must be connected to a water ground. To do this, use a 3.31 mm² (12 AWG) copper wire, which is not included with the product. This wire must be routed to a water ground location and connected to the ground connector on the pedestal. After connection, the ground screw and crimp connector must be covered with marine sealant to ensure waterproofing. It is important to note that the connection to ground must be made to a water ground and not to the negative terminal of the battery.

The GMR Fantom 12x radar pedestal is specifically designed for the Garmin GMR Fantom 12x open array radar series. It is compatible with the 4-foot and 6-foot antennas from the GMR Fantom range. This pedestal serves as a structural support and houses the electronics required for these antennas, providing superior resolution and range for detecting targets at sea.

Garmin GMR Fantom radar systems, for which this pedestal is a key component, are recognized for integrating advanced technologies that significantly enhance target detection and discrimination. These technologies include:

MotionScope™: This technology uses Doppler effect to detect and highlight moving targets, helping users quickly identify potential threats or fish schools. Pulse compression: This technology provides high resolution and excellent target detection even at long range, while optimizing transmitted energy. These innovations are crucial for safe navigation and better awareness of the marine environment.

Yes, it is strongly recommended to have the GMR Fantom 12x radar pedestal installed by a qualified marine installer. This recommendation aims to ensure the system performs optimally, avoid potential damage to the device or vessel, and above all, ensure safety. Installation involves critical considerations regarding positioning, wiring, grounding, and handling electromagnetic energy, which require specific expertise. Additionally, opening the device by anyone other than a Garmin-authorized service technician will void the product warranty.
