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

Description

Add compact pulse-compression radar coverage to a B&G navigation system with the HALO20 20-inch radar dome and included 20-meter cable. The 10W solid-state scanner fits sailboats, center consoles, and cruisers that need radar support for coastal passages, night arrivals, or low-visibility navigation without the space demands of an open array. Looking for a practical radar solution with low power draw? The HALO20 combines a 24 NM instrumented range, 4.9° beamwidth, guard-zone alarms, and MARPA support through compatible B&G multifunction displays.

Key Specifications

• B&G HALO20 20-inch solid-state pulse-compression radar dome, part number 000-14542-002.
• 10W solid-state radar without Doppler target-color processing.
• Includes a 20-meter radar cable.
• Up to 24 NM instrumented range.
• 4.9° horizontal beamwidth and 24 RPM rotation speed.
• Supports guard-zone alarms and MARPA tracking for up to 10 targets with compatible system inputs.
• Uses Ethernet for radar video and control.
• 12V or 24V DC input, approximately 18W 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 operation. NMEA 2000 can provide GPS, heading, AIS, autopilot, and other sensor information, but radar video is carried through Ethernet.

MARPA and radar overlay require compatible heading and position inputs. The stated 24 NM range is instrumented, not guaranteed target detection distance; actual results vary with radome height, target size, rain, sea clutter, weather, installation, and radar settings.

Installation Notes

Install the dome on a rigid, level mount with clear rotation and practical height above the waterline. Keep it away from crew areas, masts, rigging, antennas, lights, exhaust, and structures that can shadow or reflect radar energy. Plan the supplied 20-meter cable route before installation and protect it from heat, abrasion, standing water, high-current cables, and moving machinery.

Use properly sized power conductors and recommended circuit protection. Follow B&G installation instructions for safe distances, connector sealing, grounding, and bearing alignment. Radar is a navigation aid and does not replace visual lookout or safe navigation practices.

Before Ordering

Confirm compatible B&G MFD support, Ethernet availability, 20-meter cable-route suitability, 12V/24V power capacity, mounting clearance, and required heading/GPS sources before ordering.
