Garmin GMR xHD3 4 Antenna

Garmin GMR xHD3 4 Antenna

The Garmin GMR xHD3 4 Antenna secures high-definition target separation by resolving signal blurring issues on mid-sized offshore vessels. This 4-foot open array hardware safeguards navigation through a narrow 1.8-degree horizontal beamwidth, ensuring that the connected xHD3 pedestal identifies closely spaced navigation markers and small hazards that compact radomes miss in congested US coastal waters.

Designed for high-performance integration, this array hardware facilitates advanced bird-finding and weather tracking capabilities up to 72 nautical miles. The antenna utilizes a rugged, aerodynamic marine-grade finish to maintain consistent rotation, providing the high-gain raw data required for the radar processor to deliver 8-bit true color imaging and reliable situational awareness.
