Boat radar antenna receiver Garmin
GMR 404

The GMR 404 open array radar (pedestal sold separately; click on accessories tab to view pedestal) allows you to scan more of what's out there while you're on the water. Whether ships, shores, birds or weather, you'll see it sooner with the powerful 4-foot GMR 404 and its larger counterpart, the GMR 406.

The GMR 404 is a 4-foot open array scanner with 1.8° beamwidth and a range of 72 nautical miles. With this beamwidth and 4 kilowatts of power, the 404 offers outstanding clarity, precision and target definition. You can also use the 404 to avoid traffic on the water with MARPA target tracking.
