Raymarine E52083 48 Open Array HD Antenna

Upgrade your vessel's situational awareness with the Raymarine 48" Open Array HD Antenna, a powerhouse in marine radar technology designed for boaters who demand precision and reliability on the water. This HD digital open array scanner delivers stunning high-definition imagery, helping you spot targets—from distant vessels to small buoys—with exceptional clarity, even in cluttered coastal waters.

Superior Target Detection and Long-Range Performance

At the heart of this antenna is Raymarine's advanced HD digital processing, which minimizes sea clutter and weather interference for sharper, more interpretable returns. The generous 48-inch array size provides higher gain and narrower beamwidth compared to smaller domes, ideal for offshore adventures or navigating busy harbors. Mariners report detecting objects up to 48 nautical miles away, giving you ample time to make informed decisions during night passages or foggy conditions.

• High-Resolution Imaging: Twice the resolution of standard radars, revealing fine details like bird flocks for prime fishing spots.
• Fast Rotation Speed: Up to 48 RPM ensures smooth, real-time updates on your chartplotter.
• InstantOn™ Technology: Powers up in seconds, perfect for spontaneous outings—no long warm-up waits.

Seamless Integration with Your Marine Electronics

This open array pairs effortlessly with Raymarine's network of multifunction displays and instruments, creating a unified navigation system. Whether you're running an Axiom series plotter or legacy C/E/S models, it supports plug-and-play Ethernet connectivity via RayNet ports. For hybrid setups, it works alongside AIS, sonar, and autopilot systems, enhancing overall vessel safety.

Boat owners upgrading from radomes often notice the dramatic improvement in discrimination—separating targets that blend together on smaller scanners. It's a favorite among yacht captains and commercial operators for its robust build that withstands pounding waves and salt spray.

Engineered for Real-World Marine Demands

Crafted with marine-grade aluminum and precision-engineered radome elements, this antenna resists corrosion and maintains peak performance year after year. Low power draw keeps your batteries happy during extended cruises, while dual-voltage operation (12/24V) fits most setups. Installation is straightforward for pros: mount on a standard radar mast, route the slim interconnect cable, and calibrate via your display's intuitive wizard.

Key Scenarios Where It Shines

• Fishing Charters: Pinpoint structure and bait balls with unmatched short-range sensitivity.
• Coastal Cruising: Avoid unlit obstacles and monitor traffic in high-density areas.
• Offshore Racing: Track competitors and weather cells from afar for strategic edges.
• Search and Rescue: Crystal-clear echoes aid in spotting debris or people in the water.

Maintenance Tips for Longevity

To keep your radar humming, rinse with fresh water after saltwater exposure and inspect cables annually. Raymarine's self-diagnostic tools flag issues early, minimizing downtime. Many users report decades of service with basic care, proving its investment-worthy toughness.
