Garmin GMR 404 4 Foot Radar Array Antenna Only

Garmin Radomes and open array radar antennas show you what's out there.

Combining high-end performance and high-definition digital imaging technology at a truly affordable price, the GMR 404 xHD radar brings new value and clarity to this segment of Garmin's open array lineup.

Everything Looks Better in xHD

This 4 ft (1.22 m) scanner with a 4-kilowatt radar transmitter uses the latest in high-definition digital signal processing to deliver a dramatically sharper and clearer radar picture - with improved range resolution, target separation and clutter removal on the display. The advanced xHD electronics yield nearly 8 times more signal processing bandwidth than predecessor designs. So, you can count on improved resolution and target separation, plus better detection and presentation of small or distant returns that might go undetected on traditional analog radar systems. When installed with Garmin's GPSMAP 6000 or 7000 series network multifunction displays, the GMR 404 xHD can also display images in full color, using a multi-hued spectrum (in much the same way that your sonar fishfinder does) to indicate radar return strength or target density. Thus, whether it's birds, rocks, buoys, structures or other boat traffic on the water, you'll see more of what's out there when you scan with the GMR 404 xHD. Its maximum range is 72 nautical miles, and the selectable 24/48 RPM rotation speeds let you adapt the scan to various sea, weather or situational conditions. Optional MARPA target tracking is also supported, when installed with a Garmin heading sensor.

Easy Network Integration

The GMR 404 xHD transmits data over the Garmin Marine Network, a high-speed, plug-and-play proprietary network that makes it easy to expand your boat's system with the latest capabilities. Since all radar signal processing is contained in the remote antenna/scanner, any network-compatible Garmin chartplotter can double as your radar screen. In fact, you can overlay the GMR 404 xHD radar image on the chartplotter's map page as an aid to situational awareness. And Garmin's handy Dual Range feature enables your compatible chartplotter/MFD to display two range scans at once, so you can view close and distant targets simultaneously.

See more than before with this open array scanner

The GMR 404 open array radar antenna 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 GMR 404 and its counterpart, the GMR 406.

See Everything in Sharper Detail

The GMR 404 is a 4-foot scanner with 1.8 beamwidth and a 72 nautical mile range. With this bandwidth and 4 kilowatts of power, this radar offers outstanding clarity, precision and target definition.

Integrate with any network-compatible Garmin chartplotter

Any network-compatible Garmin chartplotter can double as your radar screen. And as an aid to locational awareness, you can overlay the GMR 404 radar image on the Garmin network's moving map cartography display. You can also split the on-screen display so that you can view the map and the standard radar page simultaneously.

Easily Connect to Garmin Marine Network

The GMR 404 communicates with the Garmin Marine Network through a waterproof 100-megabit plug-and-play proprietary network which gives you the ability to expand your boats system as needed. You can connect a GPS antenna and one remote network sensor (like the GMR 404) directly to a multifunctional display. Or, with the addition of the GMS 10 Network Port Expander, you can connect multiple displays and network sensors to the same network.
