Garmin GMR 426 xHD2 — 6-Foot Open-Array Radar System
The GMR 426 xHD2 is a complete high-definition open-array radar system that includes both the 6-foot antenna and the radar pedestal — everything needed for a full radar installation, ready to connect to a compatible Garmin GPSMAP chartplotter. With 4kW of transmit power and a 72-nautical-mile range, it delivers the long-range detection and sharp target separation needed for serious offshore navigation, commercial use, and demanding coastal conditions.
The 6-foot array provides superior beam sharpness and target resolution compared to shorter antennas or dome radars, and the xHD2 high-definition processing delivers clear, detailed radar returns in rain, sea clutter, and low-visibility conditions. At 48 RPM, the picture updates rapidly enough to track fast-moving targets and navigate confidently in busy waterways.
It connects to compatible Garmin GPSMAP chartplotters via the Garmin Marine Network (Ethernet), overlaying radar returns directly on chart data for a clear, integrated situational picture.

Parts Desk Insights
Best Use Case: The GMR 426 xHD2 complete kit is the right choice for offshore fishing boats, larger cruisers, and commercial vessels where maximum radar range and target resolution are the priority and you want a single-purchase, complete radar solution. The 4kW/6-foot combination delivers the best long-range performance in the xHD2 magnetron lineup — 72nm range with the beam sharpness of a 6-foot array. Compared to the GMR CHIRP 2106, the 426 xHD2 offers greater maximum range at the cost of close-range target discrimination; the CHIRP system excels at short range while the 426 xHD2 is the stronger performer at distance. Buying the complete kit avoids the compatibility risk of sourcing antenna and pedestal separately. Confirm your Garmin GPSMAP chartplotter supports the Garmin Marine Network (Ethernet) before ordering, and ensure your radar arch or mast is rated for a 6-foot array’s weight and wind load.
Installation Note: Ships as two cartons — the 6-foot antenna in a long carton and the pedestal separately. Professional installation is strongly recommended for a system at this level. Ensure all Garmin Marine Network cable runs use quality shielded Ethernet cable.
Estimated Packaging: Two cartons — antenna approximately 80" × 12" × 8" (203 × 30 × 20 cm) and pedestal approximately 16" × 16" × 12" (41 × 41 × 30 cm), approx. 18 kg total shipped. Oversized freight shipping required.
