The Garmin GMR xHD2 4' Open Array is a high-definition radar antenna designed to be paired with Garmin's xHD2 or Fantom series pedestals. Measuring 4 feet (approx. 1.2 meters) in length, this antenna provides a professional 1.8-degree horizontal beamwidth, offering a perfect balance between size and high-resolution target separation. It is the ideal choice for offshore anglers and cruisers who need to identify small targets or birds at a distance while maintaining a manageable footprint on the boat's hardtop or radar arch.

Professional Target Separation
The GMR xHD2 4' antenna array significantly improves your radar's ability to separate two close targets, which might appear as one single target on smaller dome radars. With a 1.8-degree beam, it provides high-resolution imaging that is vital for navigating crowded marinas or detecting birds on the horizon. Whether you're upgrading an existing xHD2 system or completing a new Fantom install, this 4-foot array delivers the precision Garmin mariners expect.
Frequently Asked Questions
1. Is this compatible with a GMR Fantom pedestal?
Yes. This antenna array is interchangeable and fully compatible with both GMR xHD2 (magnetron) and GMR Fantom (solid-state) Garmin radar pedestals.
2. Can I use this on a smaller boat?
While 4 feet is more compact than the 6-foot version, it still requires a sturdy mounting surface. It is popular for sportfishing boats 25-35 feet where a 6-foot array might be too large.
