Radom Garmin GMR Fantom™ 24x, must

Yes, the GMR Fantom™ 24x radome uses Garmin BlueNet™ network technology and is compatible with Garmin BlueNet devices as well as Garmin Marine Network devices.

If your boat is equipped with a Garmin BlueNet chartplotter, you can connect the radome directly to an open network port on the chartplotter or to a Garmin BlueNet 20 switch using the included Garmin BlueNet cable.

If your boat is equipped only with Garmin Marine Network devices, you will need to use a Garmin Marine Network adapter cable (part number 010-12531-01, sold separately if not included) to connect the radome to your network.

When mounting the radome on a roof or hardtop, it is crucial to elevate it sufficiently to avoid interference with the surface. The beam transmitted by this radar extends vertically at 12.5 degrees from the horizontal centerline. You should therefore raise the dome so that the beam passes above the edge of the roof or hardtop. Using a base or another suitable structure may be necessary to achieve the required installation height.

The GMR Fantom™ 24x radome requires an input voltage between 10 and 32 VDC (Volts Direct Current).

The status LED located on the product label provides information about the radar's operation:

Solid red: The radar is powering up. This light should only remain red briefly before switching to flashing green.Flashing green: The radar is operating correctly.Flashing orange: The radar's software is being updated.Flashing red: The radar has encountered an error. Check the connected chartplotter to see if an error message is displayed.

Yes, it is mandatory to update the software of your Garmin chartplotter when installing this radome. Detailed instructions for the software update are available in your chartplotter’s user manual.

Several safety precautions are essential when installing the radar:

Installation by a qualified marine installer is recommended for optimal performance and to avoid injury or damage. Never remove the inline fuse when connecting the power cable. The appropriate fuse must be in place to prevent fire or overheating risks. Do not look directly at the antenna at close range while the radar is transmitting, as the eyes are the most sensitive part of the body to electromagnetic energy. To prevent potential injuries, always wear safety glasses, hearing protection, and a dust mask when drilling, cutting, or sanding. Opening the device by anyone other than a Garmin-authorized service technician voids the Garmin warranty.

To mount the GMR Fantom™ 24x radome, follow these steps:

Use the included mounting template to drill four 9.5 mm (3/8 in) mounting holes.Apply the provided anti-seize compound to the threads of the four M8 x 1.25 x 60 studs.Insert the four studs into the mounting holes under the radome. These studs accommodate mounting thicknesses from 5 to 30 mm (3/16 to 1 3/16 in). For surfaces thicker than 30 mm, use longer studs.Apply a bead of marine sealant around each mounting hole on the mounting surface.Attach the radome to the mounting surface using the studs, flat washers, spring washers, and hex nuts.Tighten the nuts to a torque of 13.7 to 18.6 N·m (10 to 14 lbf-ft) using a torque wrench.

The Garmin GMR Fantom™ 24x radome is a 24-inch marine radar system designed for advanced target detection. It is part of the current Fantom range and integrates Garmin BlueNet™ network technology for fast connectivity. It is also compatible with Garmin Marine Network systems via an optional adapter cable.

To install the GMR Fantom™ 24x radome, you will need the following tools:

A drillA 9.5 mm (3/8 in) drill bitA 32 mm (1 1/4 in) drill bit (optional, for cable routing)A 4 mm (5/32 in) Allen keyA 13 mm (1/2 in) wrench and torque wrenchMarine sealant

For optimal performance and safety, the radome must be mounted considering the following points:

It is strongly recommended to mount it out of reach of personnel, with the horizontal beam above head height.The unit must be mounted high above the vessel's keel line, with minimal obstruction between the vessel and the radar beam.The mounting surface must be flat, parallel to the vessel's waterline, and sufficiently robust to support the unit's weight.The radome must be mounted away from heat sources (exhausts, lights) and at a different level from horizontal spreaders and transverse mast bars.Other electronic equipment and cables must be mounted more than 2 meters (6 ½ feet) from the radar beam path.GPS antennas must be located either above or below the radar beam path.The radome must be mounted at least 1 meter (40 inches) from any transmitting equipment and cables carrying radio signals (VHF, etc.). For HF radios (SSB), this distance must be increased to 2 meters (6 ½ feet).

To mount the radome, follow these steps:

If you are not using a pre-drilled Garmin radar mount, use the included mounting template to drill four 9.5 mm (3/8 in) mounting holes.Connect the network cable to the network port and the power cable to the power port.Thread the cables through the cable guides under the housing and secure them with the cable retainer plate.Position the radome on the mounting surface, aligning it with the bow of the vessel (any offset can be adjusted later).Apply the provided anti-seize compound to the threads of the four M8 x 1.25 x 60 threaded rods.Insert the threaded rods into the mounting holes under the radome.Apply a bead of marine sealant around each hole on the mounting surface.Secure the radome to the mounting surface using the threaded rods, flat washers, spring washers, and hex nuts.Tighten the nuts using a torque wrench to 13.7–18.6 N·m (10–14 lbf·ft).

Yes, it is possible to install the radar on a roof or hardtop. However, it is important to note that you may need to raise the installation height using a pedestal or another suitable structure. This helps avoid a negative impact on performance, as the beam transmitted by the radar propagates vertically at 12.5 degrees from the horizontal centerline. Raising the dome ensures that the beam clears the edge of the roof or hardtop, preventing the transmitted energy from being reflected or absorbed by the surface, especially if it is metallic.

When installing cables, take the following precautions:

Use appropriate cable ties, fasteners, and sealant to secure the cable along its route and through bulkheads or the deck.Avoid running cables near moving objects, high heat sources, or through doors and bilges.To prevent interference with other equipment, do not run network and power cables parallel to other cables (radio antenna lines, power cables). If this is unavoidable, shield the cables with a metal conduit or EMI shielding.Install the power cable as close as possible to the battery source. If an extension is required, use the appropriate wire gauge based on the extension length (e.g., 16 AWG for 2 m, 14 AWG for 4 m, 12 AWG for 6 m).Do not forget to apply marine sealant around cable pass-through holes to ensure perfect watertightness.

The GMR Fantom™ 24x radome uses Garmin BlueNet™ network technology and is compatible with both Garmin BlueNet devices and Garmin Marine Network devices. For optimal performance and to support future updates, it is recommended to connect it to the BlueNet side of your network if you have a Garmin BlueNet chartplotter.

The GMR Fantom™ 24x radome is supplied with a Garmin BlueNet™ cable. To connect the radar to a Garmin BlueNet network, route this cable to the GMR Fantom™ 24x unit and to your Garmin BlueNet chartplotter or Garmin BlueNet 20 switch. Connect one end of the BlueNet cable to the network port on the radome and the other end to any open network port on your BlueNet chartplotter or BlueNet 20 switch. Ensure the locking collars on the connectors are tightened.

If your boat is equipped only with Garmin Marine Network devices, you will need to use a Garmin Marine Network adapter cable to connect the GMR Fantom™ 24x radome to your network. If this adapter cable is not included in the product box, you can purchase it (reference 010-12531-01).

The GMR Fantom™ 24x radome operates with an input voltage between 10 and 32 Vdc. Its operating temperature range is from -15 to 70°C (5 to 158°F).

It is mandatory to update the software of your Garmin chartplotter when installing the GMR Fantom™ 24x radome. To obtain the software update instructions, refer to your chartplotter's owner manual on support.garmin.com.

Yes, opening the device by anyone other than a Garmin authorized service technician may result in personal injury and/or damage to the device, and will not be covered under the Garmin warranty. The device contains no user-serviceable parts and must only be opened by a Garmin authorized service technician.

Yes, the GMR Fantom™ 24x radome is supplied with a mounting template. This template is useful for drilling the four 9.5 mm (3/8 in) mounting holes if you are not installing the unit on a pre-drilled Garmin radar mount.
