Garmin GMR Fantom 6 Antenna Array Only – Black

Description

The Garmin GMR Fantom 6 Foot Open Array Antenna in Black is a replacement antenna radiator for compatible Garmin Fantom open-array radar pedestals. This six-foot black antenna array is not a complete radar system and does not include a pedestal, transmitter, display, radar power cable, Garmin Marine Network cable, mounting platform, heading sensor, or GPS source. When paired with a compatible Fantom pedestal, its narrow 1.25-degree horizontal beamwidth supports the antenna pattern used by the completed radar scanner.

The antenna measures approximately 193.8 cm, or 76.3 inches, long and weighs approximately 7.3 kg, or 16 lb. It is designed for compatible Garmin Fantom 56, Fantom 126, and other approved six-foot open-array pedestal configurations. Transmit power, instrumented range, Doppler capability, rotation speed, Bird Gain, MARPA, and radar features depend on the selected pedestal and compatible Garmin display system.

Key Specifications

• Six-foot black Garmin Fantom open-array radar antenna radiator only.
• Requires a separately selected compatible Garmin Fantom radar pedestal.
• Measures approximately 193.8 cm, or 76.3 inches, in length.
• Weighs approximately 7.3 kg, or 16 lb, as an antenna-only component.
• Provides approximately 1.25-degree horizontal and 22-degree vertical beamwidth when paired with a compatible pedestal.
• Uses an end-fed slotted-waveguide antenna design with horizontal polarization.
• Does not include a pedestal, radar transmitter, chartplotter, power cable, Garmin network cable, mount, heading sensor, or GPS source.
• Radar output, range, rotation speed, MotionScope Doppler, Bird Gain, target tracking, and other functions depend on the matching pedestal and display.

Radar Integration

This antenna must be paired with a compatible Garmin Fantom pedestal and a supported Garmin chartplotter or MFD connected through Garmin Marine Network or Garmin BlueNet. NMEA 2000 can provide compatible heading, GPS, AIS, autopilot, and sensor data to the completed system but does not carry radar video.

The antenna alone does not transmit radar energy, receive radar returns, display targets, or provide Doppler, MARPA, radar-overlay, or navigation functions. Radar is a navigation aid and does not replace a proper lookout, safe speed, official charts, local notices, or collision-regulation compliance.

Installation Considerations

Install the completed pedestal-and-array scanner on a rigid level platform with full six-foot rotation clearance. Mount at a practical height above the waterline, align the array parallel to the waterline, and keep it clear of people, masts, rigging, antennas, lights, exhaust, and other obstructions. Maintain manufacturer-specified personnel safe distance and compass-safe distance for the complete radar system. Radar installation and commissioning should be completed by a qualified marine-electronics technician.

Warranty and Saltwater Care

Garmin marine warranty coverage varies by region, distributor, proof of purchase, product registration, installation method, and intended use. Confirm applicable local warranty terms, exclusions, registration requirements, and service process before purchase.

The antenna is designed for marine exposure, but long-term saltwater durability depends on correct mounting, drainage, compatible fasteners, regular inspection, and manufacturer-approved maintenance. Rinse salt deposits with fresh water where appropriate, inspect the radiator surface, pedestal joint, attachment hardware, fasteners, and mounting platform regularly, and use compatible marine-grade hardware plus approved isolation methods to reduce galvanic-corrosion risk.

Before Ordering

Confirm the exact compatible Garmin Fantom pedestal, supported Garmin MFD, Garmin Marine Network or BlueNet connection, six-foot array rotation clearance, mounting-platform strength, wind-load suitability, mounting height, personnel and compass-safe-distance requirements, required power and network cables, heading and GPS source for MARPA or radar overlay, and qualified installation requirements before purchase.
