Simrad HALO20+ – 20-Inch Pulse Compression Radar Dome

Description

Improve Doppler-assisted target awareness in a compact radome with the Simrad HALO20+ 20-Inch Pulse Compression Radar. Its 25W solid-state output, VelocityTrack target coloring, and scan speeds up to 60 RPM help boaters follow traffic, shorelines, and weather returns during harbor departures, coastal crossings, and night runs. Need independent short- and long-range radar views without an open-array scanner? The HALO20+ supports dual-range operation, MARPA tracking, Ethernet integration, and up to 36 NM of instrumented range.

Key Specifications

• Simrad HALO20+ 20-inch solid-state pulse-compression radar radome.
• 25W solid-state radar output.
• Up to 36 NM instrumented range and approximately 20 ft (6 m) minimum range.
• 4.9° horizontal beamwidth and 25° vertical beamwidth.
• Rotation speeds up to 60 RPM with InstantOn capability.
• VelocityTrack Doppler target coloring and independent dual-range operation.
• Supports MARPA tracking for up to 10 targets when compatible heading and position data are available.
• Ethernet connectivity through RJ45 with the required adapter arrangement.
• 10.5V–31.2V DC input, approximately 20W typical draw, up to 29W peak draw, and about 5W standby draw.
• IPX6 protection, 100-knot wind rating, and approximately 13 lb (5.9 kg) weight.

Integration

The HALO20+ requires a compatible Simrad MFD and Ethernet network connection for radar video and control. NMEA 2000 can supply compatible GPS, heading, AIS, autopilot, and sensor data, but it does not carry radar video. MARPA and radar overlay require valid heading and position inputs.

VelocityTrack can help distinguish relative target movement through color-coded radar returns, but it does not guarantee target identification or collision avoidance. The 36 NM rating is instrumented range; real-world results vary with scanner height, target characteristics, rainfall, weather, sea state, clutter, settings, and installation quality.

Installation Notes

Mount the radome on a rigid, level platform with clear scanner rotation and a practical view around the vessel. Keep it away from personnel, masts, antennas, rigging, lights, exhaust, and structures that can create radar shadow sectors. Route power and Ethernet connections through protected paths away from heat, abrasion, water, high-current cables, and moving equipment.

Use correctly sized wiring and recommended circuit protection. Follow Simrad instructions for safe distances, connector sealing, network setup, and radar alignment. Radar is a navigation aid and does not replace visual lookout, safe speed, charts, or compliance with navigation rules.

Before Ordering

Confirm compatible Simrad MFD support, Ethernet connection availability, required adapters, 12V/24V power capacity, mount strength, radome clearance, and heading/GPS sources for MARPA or radar overlay before ordering.
