Garmin GMR Fantom 4 Antenna Array Only

Description

Replace a worn or damaged 4-foot radar radiator while keeping a compatible Garmin Fantom pedestal in service with the Garmin GMR Fantom 4-Foot Open Array Antenna in White. The 52-inch array is intended for boaters who need the physical antenna component—not a complete radar package—for an existing Fantom installation. Need a white replacement array with a compact sweep footprint? This antenna-only assembly provides a 1.85° horizontal beamwidth and 22° vertical beamwidth when paired with a supported Garmin Fantom pedestal.

Compatibility

This replacement array cannot transmit, receive, or display radar information by itself. A compatible Garmin Fantom pedestal provides the radar drive and electronics, while a supported Garmin chartplotter or MFD provides radar display and control through Garmin Marine Network or a compatible Garmin BlueNet setup.

The 4-foot array’s 1.85° beamwidth supports bearing separation for the completed scanner. Range, transmit power, MotionScope Doppler, MARPA, Bird Mode, echo trails, rotation speed, and other radar functions are determined by the matched pedestal, display, sensors, and software—not by the array alone.

Installation Notes

Mount the array only on an approved compatible Fantom pedestal installed on a rigid, level platform. Provide full 4-foot sweep clearance and keep the scanner away from people, masts, rigging, antennas, lights, exhaust, and structures that could obstruct radar energy or create shadow sectors.

Use marine-grade fasteners, follow Garmin torque values, and inspect the pedestal-to-array connection routinely. Rinse salt residue when appropriate, avoid high-pressure spray on antenna joints or seals, and address corrosion or loose hardware promptly. Radar remains a navigation aid and does not replace a proper lookout or safe navigation practices.

Before Ordering

Confirm the pedestal model, compatible Garmin MFD, network setup, 4-foot sweep clearance, mounting-platform strength, wind-load suitability, and required installation hardware before ordering.
