Garmin GMR Fantom 18x Dome Radar – Black

Description

The Garmin GMR Fantom 18x Dome Radar in Black, SKU 010-02584-01, is an 18-inch solid-state marine radar radome with MotionScope Doppler technology. It is designed for compatible Garmin chartplotters and multifunction displays using Garmin Marine Network Ethernet. The compact enclosed radar dome provides CHIRP pulse-compression performance, Doppler target highlighting, selectable rotation speeds up to 60 RPM, and a maximum instrumented range of 48 NM.

The GMR Fantom 18x requires a compatible Garmin chartplotter, Garmin Marine Network connection, suitable radar mount, and correctly sized 10V to 32V DC power supply. It is a radar scanner rather than a chartplotter; charts, GPS data, heading source, AIS, and other navigation sensors are separate system components. Practical target detection varies with mounting height, target size, weather, sea state, interference, and radar settings.

Key Specifications

• Garmin 18-inch black solid-state radar radome, SKU 010-02584-01.
• Uses CHIRP pulse-compression radar and MotionScope Doppler target-highlighting technology.
• Provides 50W solid-state transmit power and a 48 NM maximum instrumented range.
• Uses a 5.2-degree horizontal beamwidth for compact radome target separation.
• Supports selectable antenna rotation speeds up to 60 RPM.
• Supports compatible MARPA, echo trails, guard zones, and radar-overlay functions when system requirements are met.
• Operates from 10V to 32V DC with listed typical consumption of 24W transmitting and 7W in standby.
• Weighs approximately 5.9 kg and has IPX7 protection for a compatible radar mounting location.

Radar Integration

The Fantom 18x requires a compatible Garmin chartplotter or MFD and Garmin Marine Network Ethernet connection for radar display and control. NMEA 2000 can provide compatible GPS, heading, AIS, autopilot, and other sensor data, but it is not the radar-video network. A compatible heading sensor and GPS source are required for functions such as radar overlay and MARPA target tracking.

MotionScope Doppler processing can help highlight moving targets, subject to target motion, scanner settings, sea clutter, rain, and operating conditions. Radar is a navigation aid and does not replace a proper lookout, safe speed, official charts, local notices, or collision-regulation compliance.

Installation Considerations

Mount the 18-inch radome on a rigid stable platform with a clear rotating zone, aligned parallel to the waterline and clear of antennas, lights, masts, exhaust, rigging, and crew movement. Install above head height where practical and maintain the manufacturer-specified personnel safe distance and compass-safe distance. Route power and Garmin Marine Network cables away from heat, water accumulation, chafe, high-current wires, and moving equipment. Radar installation and commissioning should be completed by a qualified marine-electronics technician.

Before Ordering

Confirm compatible Garmin chartplotter support, Garmin Marine Network connection, 10V to 32V supply, suitable radome mount, clear 18-inch scanner rotation area, mounting height, safe-distance requirements, radar cable needs, heading and GPS source for MARPA or radar overlay, optional AIS integration, and qualified installation requirements before purchase.
