Radómdúkur GMR Fantom™ 18x, hvítur

The Garmin GMR Fantom™ 18x radome uses solid-state pulse compression technology. This approach differs from traditional magnetron radars and delivers advanced performance.

The GMR Fantom™ 18x semiconductor technology offers several significant advantages:

Instant start-up.Reduced power consumption.Optimized target detection at both short and long range.

Yes, the GMR Fantom™ 18x radome is designed for flexible integration. It is compatible with Garmin BlueNet™ chartplotters and the Garmin BlueNet 20 switch. For existing systems equipped only with Garmin Marine Network devices, compatibility is maintained using a Garmin Marine Network adapter cable (reference 010-12531-01, if not included).

To connect the GMR Fantom™ 18x to an existing Garmin Marine Network, you must use the Garmin Marine Network adapter cable. The part number for this item is 010-12531-01.

When installing the GMR Fantom™ 18x radome, several safety precautions are essential:

The radome must be mounted out of reach of personnel, with the horizontal beam above head height. Ensure all personnel are clear of the radar beam before transmission.

To avoid injury, do not look directly at the antenna at close range when the radar is transmitting.

When connecting the power cable, do not remove the inline fuse holder. An appropriate fuse must be installed.

When drilling, cutting, or sanding, always wear safety glasses, hearing protection, and a dust mask.

It is also recommended that installation be performed by a qualified marine installer.

Yes, it is mandatory to update the Garmin chartplotter software when you install the GMR Fantom™ 18x radome. This ensures compatibility and proper operation of the device.

For correct installation of the radome, the following tools are recommended:

A drill with 9.5 mm (3/8 in) bits and optionally 32 mm (1 1/4 in) bits.A 4 mm (5/32 in) Allen key.A 13 mm (1/2 in) wrench and a torque wrench.Marine sealant.

For optimal performance, the radome must be mounted following these guidelines:

At a height above the keel line of the vessel, with minimal obstructions between the vessel and the radar beam.On a flat surface or platform that is parallel to the vessel’s waterline and sufficiently robust to support the device’s weight.Away from heat sources (exhausts, lights) and at a different level from horizontal spreaders and mast bars.

The radar beam propagates vertically at 12.5° above and 12.5° below the radiating element of the radome. On vessels with higher stem angles at cruising speed, the installation angle can be slightly lowered to aim the beam toward the static waterline. Shims may be used if necessary to adjust this angle.

To avoid interference and ensure safety, respect the following distances:

The device must be mounted out of reach of personnel, with the horizontal beam above head height.Keep the radome away from magnetic compasses (according to the safety distance specified in the product specifications).Other electronic devices and cables must be mounted more than 2 m (6.5 ft) from the radar beam path.GPS antennas must be either above or below the radar beam path.The radome must be mounted at least 1 m (40 in) from any transmitting equipment.Maintain a distance of at least 1 m (40 in) from cables carrying radio signals (VHF, etc.). For SSB radios, increase this distance to 2 m (6.5 ft).

Yes, it is possible to install the radar on a roof or hard-top. However, it may be necessary to increase the installation height using a stand or another suitable structure. This helps avoid a negative impact on performance, as direct mounting could result in reflection or absorption of the transmitted energy by the surface, especially if it is metallic.

For radome mounting, you will need to drill four mounting holes of 9.5 mm (3/8 in). For cable routing, holes of 32 mm (1 1/4 in) may be required. It is important to use the included mounting template to ensure accuracy.

To ensure perfect watertightness, apply marine sealant around the hole after cables are in place. Decorative 32 mm (1 1/4 in) cable glands are available as an option, but they do not provide waterproofing on their own and also require marine sealant application.

It is critical not to remove the inline fuse holder from the power cable. Connecting the power cable without the appropriate fuse, as specified in the product documentation, voids the product warranty and may pose fire or overheating hazards.

No, the GMR Fantom™ 18x radome contains no user-repairable parts. The unit must only be opened by a technician authorized by Garmin. Any damage resulting from the unit being opened by someone other than a Garmin-authorized technician will not be covered by the warranty.

A status LED (light-emitting diode) on the product label can help you verify its operation:

A flashing green LED indicates the radar is functioning correctly. A steady red LED means the radar is in standby mode. A flashing orange LED means the radar software is being updated. A flashing red LED signals an error; you will then need to check the connected chartplotter for an error message.

No, this device must be used solely as a navigation aid. Using the device for purposes requiring precise measurement or direction, distance, location, or topography may result in bodily injury or damage to the vessel.
