Garmin GMR 1236 xHD3 6 Open Array Radar & Pedestal – 12kW

The Garmin GMR 1236 xHD3 high definition open array radar tracks distant targets instantly when offshore vessels voyage through low-visibility blue waters. Thick coastal fog and sudden maritime squalls regularly hide smaller vessels, blinding traditional commercial receivers. Installing this ultra-high-definition magnetron system delivers outstanding target detection, preventing hazardous collision incidents during offshore navigation transit lines safely.

This high definition magnetron radar utilizes a powerful 12kW peak power transmitter core network. Unlike lower-tier closed radomes that lose target focus near the horizon, this open array radar antenna delivers an ultra-sharp 1.1-degree horizontal beamwidth across a 72 nautical mile range. The heavy duty cast pedestal achieves an IPX6 waterproofing standard, fully isolating internal components from saltwater spray during long-range target identification runs.

Why Choose This Radar over Generic Alternatives

Selecting the specialized Garmin GMR 1236 xHD3 open array package is ideal for professional sportfishing captains requiring extreme azimuth target separation. Unlike basic radomes that blur close echoes under high wind loads, this 6ft array focuses micro-pulses perfectly. It coordinates seamlessly across your Garmin Marine Network, ensuring offshore motor yachts avoid unexpected navigation drops across busy commercial shipping lanes safely.

Application & Limitations

This 12kW open array radar system delivers top-tier performance on blue-water sportfishers, luxury motor yachts, and commercial coastal craft. However, because its combined pedestal and 6ft antenna profile generate a total weight load of 48.3 lbs, it cannot mount onto unreinforced canvas arches safely. Additionally, its transmitter draws 85 Watts during active processing, requiring a steady 10V-32V DC electrical input rail setup.
