Lowrance HALO20 – 20-Inch Pulse Compression Radar Dome

Description

Add compact solid-state radar coverage to a compatible Lowrance navigation system with the Lowrance HALO20 20-Inch Radar Dome. Its pulse-compression design, 24 RPM scan speed, and 24 NM instrumented range make it a practical choice for center consoles, fishing boats, and cruisers that need radar awareness without an open-array installation. Need a low-power radome for watching nearby traffic and shoreline returns? The HALO20 connects through Ethernet, supports MARPA with compatible navigation data, and starts without the warm-up routine of a magnetron radar.

Key Specifications

• Lowrance HALO20 20-inch solid-state pulse-compression radar radome.
• 20W solid-state transmitter output.
• Up to 24 NM instrumented range with approximately 20 ft (6 m) minimum range.
• 4.9° horizontal and 25° vertical beamwidth.
• 24 RPM scanner rotation speed.
• Supports MARPA tracking for up to 10 targets when compatible heading and position data are available.
• Standard HALO20 model does not include Doppler target coloring or dual-range operation.
• Ethernet connection through RJ45.
• 12V/24V DC input, approximately 18W typical draw, 27W maximum draw, and 3.9W standby draw.
• IPX6 protection, 100-knot wind rating, and approximately 13 lb (5.9 kg) weight.

Integration

The HALO20 requires a compatible Lowrance MFD and Ethernet connection for radar control and video. NMEA 2000 can provide compatible heading, GPS, AIS, autopilot, and sensor data, but radar video is carried through Ethernet. MARPA and radar overlay require valid heading and position information.

Lowrance documents the HALO20 with a 20-inch dome, range settings from 100 m to 24 NM, 9V–31.2V DC input at the scanner, and 3.9W typical standby power. [920] The stated 24 NM range is an instrumented range and does not guarantee detection distance in all conditions.

Installation Notes

Install the radome on a rigid, level platform with clear rotation and minimal obstruction from antennas, masts, lights, rigging, exhaust, and other structures. Keep the scanner clear of people and follow manufacturer-specified safe distances. Route power and Ethernet cables through protected paths away from heat, chafe, bilge water, high-current conductors, and moving equipment.

Use the correct cable, circuit protection, network components, and grounding practices. Follow Lowrance installation guidance for bearing alignment and software setup. Radar is a navigation aid and does not replace lookout duties, safe speed, charts, or navigation-rule compliance.

Before Ordering

Confirm compatible Lowrance MFD support, Ethernet network availability, 12V/24V power capacity, radome mounting space, 20-inch sweep clearance, cable length, heading/GPS sensor needs, and professional installation requirements before ordering.
