Furuno XN12A/4 4 Foot Open Array Radar Antenna

Description

The Furuno XN12A/4 4 Foot Open Array Radar Antenna is an open-array radiator bar for compatible Furuno DRS and commercial radar pedestals. It is an antenna-only component and must be paired with a matching Furuno pedestal, transmitter, scanner drive, radar cable, display or processor, power system, and mounting platform. The four-foot array provides a narrow horizontal beam pattern for compatible Furuno marine radar systems.

The antenna measures approximately 1,219 mm, or four feet, and weighs approximately 5 kg. Its listed 1.9-degree horizontal beamwidth can improve angular target separation when paired with the appropriate scanner. Output power, rotation speed, maximum instrumented range, radar technology, display compatibility, target tracking, and network functions depend entirely on the selected Furuno pedestal and complete radar system.

Key Specifications

• Four-foot Furuno open-array radar antenna radiator only.
• Requires a separately selected compatible Furuno DRS or commercial radar pedestal.
• Provides approximately 1.9-degree horizontal and 22-degree vertical beamwidth when paired with a compatible scanner.
• Measures approximately 1,219 mm, or four feet, and weighs approximately 5 kg.
• Receives operating power and scanner drive from the compatible radar pedestal.
• Does not include a radar transmitter, pedestal, power supply, radar cable, chartplotter, radar display, processor, or mounting platform.
• Radar output power, range, rotation speed, radar technology, target tracking, and display features depend on the paired pedestal.
• Requires a rigid radar platform with sufficient open-array rotation clearance and appropriate wind-load capacity.

Radar Integration

This radiator must be paired with a compatible Furuno radar pedestal and supported display or radar processor. It does not transmit radar energy or supply radar video by itself. Radar-video networking, GPS, heading, ARPA, target tracking, and radar-overlay functions depend on the complete Furuno radar system and the connected compatible equipment.

Confirm the exact Furuno scanner model, pedestal gear drive, antenna attachment method, compatible display, radar cable, power requirements, and heading source before purchase. 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 radar scanner on a rigid level platform with full four-foot array rotation clearance. Mount it at a practical height above the waterline, align it parallel to the waterline, and keep it clear of crew areas, mast structures, rigging, antennas, lights, exhaust, and other obstructions. Maintain manufacturer-specified personnel safe distance and compass-safe distance for the complete system. Radar installation and commissioning should be completed by a qualified marine-electronics technician.

Warranty and Saltwater Care

Furuno warranty coverage varies by region, distributor, proof of purchase, commissioning status, installation method, and intended use. Confirm the applicable local warranty terms, exclusions, and authorized-service requirements before purchase.

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

Before Ordering

Confirm the exact compatible Furuno pedestal, radar scanner, display or processor, radar cable, antenna attachment method, four-foot rotation clearance, platform strength, wind-load requirement, mounting height, personnel and compass-safe-distance requirements, and qualified installation requirements before purchase.
