Garmin GMR Fantom 4 Antenna Array Only – Black

Description

Replace a damaged or weathered open-array radiator without rebuilding the entire radar system with the Garmin GMR Fantom 4-Foot Open Array Antenna in Black. This 52-inch replacement array gives boat owners a practical way to restore a compatible Fantom scanner while maintaining a compact 4-foot sweep footprint. Need a matched array for a Fantom 5x, 12x, or 25x pedestal? This antenna-only component delivers a 1.85° horizontal beamwidth and 22° vertical beamwidth when installed on a compatible Garmin pedestal.

Compatibility

This is a replacement antenna array, not a complete radar. A compatible Garmin Fantom pedestal supplies transmit and receive functions, while a compatible Garmin chartplotter displays radar video and controls the scanner through Garmin Marine Network or a compatible Garmin BlueNet configuration.

The 1.85° beamwidth is determined by the 4-foot array and helps separate targets that are close together in bearing. Radar range, transmit power, MotionScope Doppler, MARPA, Bird Mode, echo trails, rotation speed, and other operating features depend on the paired pedestal, connected display, sensors, and software configuration.

Installation Notes

Install the antenna on an approved Fantom pedestal mounted to a rigid, level radar platform. Allow full clearance for the 4-foot rotating array and keep the scanner clear of people, rigging, antennas, lights, exhaust, and structures that could block or reflect radar energy. Follow the pedestal installation manual for personnel safe distances, compass-safe distances, torque values, and electrical requirements.

Use marine-grade mounting hardware and inspect the pedestal-to-array connection regularly. Rinse salt residue with fresh water when appropriate, avoid high-pressure spray at joints and seals, and address corrosion, loose fasteners, or damaged hardware promptly. Radar is a navigation aid and does not replace a proper lookout, safe speed, charts, or collision-regulation compliance.

Before Ordering

Confirm the exact Fantom pedestal model, compatible Garmin chartplotter, radar-network setup, 4-foot rotation clearance, platform strength, wind-load suitability, and required installation hardware before ordering.
