B&G HALO20+ 20 Radar Dome w/20M Cable

Description

Help make moving radar targets easier to notice with the B&G HALO20+ Doppler Radar Dome, a compact 20-inch scanner with an included 20-meter cable. VelocityTrack Doppler coloring, a 36 NM instrumented range, and rotation speeds up to 60 RPM give sailors and powerboat operators responsive target awareness for harbor exits, coastal crossings, and pre-dawn departures. Want more than basic radar returns from a compact dome? The HALO20+ blends 25W solid-state pulse compression with dual-range capability and B&G Ethernet integration for compatible MFD systems.

Key Specifications

• B&G HALO20+ 20-inch solid-state Doppler radar dome, part number 000-14541-002.

• Uses Ethernet for radar video and control.
• 10.5V–31.2V DC input, approximately 20W transmit draw, and 7W standby draw.
• IPX6 protection and approximately 13 lb (5.9 kg) weight.

Integration

The HALO20+ requires a compatible B&G multifunction display and Ethernet connection for radar display and scanner control. NMEA 2000 can provide compatible GPS, heading, AIS, autopilot, and sensor data, but it does not carry radar video.

VelocityTrack can help distinguish approaching and diverging targets through color-coded returns. MARPA and radar overlay require compatible position and heading inputs. The 36 NM specification is instrumented range, and real-world performance changes with target characteristics, scanner height, weather, rainfall, sea state, clutter, and installation quality.

Installation Notes

Mount the 20-inch dome on a stable, level platform with clear rotation and minimal blockage. Keep it clear of people, antennas, lights, masts, rigging, exhaust, and structures that can produce shadow sectors. Route the supplied 20-meter cable through protected paths away from heat, chafe, bilge water, moving equipment, and high-current wiring.

Follow B&G requirements for power protection, network connections, safe distances, and radar alignment. Radar is a navigation aid and does not replace a proper lookout, safe speed, official charts, or compliance with navigation rules.

Before Ordering

Confirm compatible B&G MFD support, Ethernet connection, 20-meter cable path, 10.5V–31.2V DC power supply, mounting clearance, and heading/GPS availability for MARPA or radar overlay before ordering.
