Lowrance HALO20+ 20 Radar Dome w/5M Cable

Description

The Lowrance HALO20+ 20 Radar Dome with 5 m Cable is a compact solid-state pulse-compression radar radome for compatible Lowrance multifunction displays. Its 20-inch enclosed scanner uses VelocityTrack Doppler technology to help distinguish approaching and diverging targets with color highlighting, while dual-range operation allows simultaneous monitoring of two radar ranges. The package includes a five-meter radar cable for installations where the scanner and display or radar module are located close together.

The HALO20+ has a maximum instrumented range of 36 NM, a 4.9-degree horizontal beamwidth, and rotation speeds up to 60 RPM. It requires a compatible Lowrance display, Ethernet radar connection, suitable radar mount, and correctly protected 12V or 24V power supply. Practical detection distance depends on mounting location, antenna height, target size, weather, sea clutter, radar settings, and local conditions.

Key Specifications

• Twenty-inch solid-state pulse-compression marine radar radome for compatible Lowrance displays.
• Includes a five-meter radar power and Ethernet cable for shorter scanner-to-system cable routes.
• Uses VelocityTrack Doppler technology to help highlight approaching and diverging targets.
• Provides dual-range operation for simultaneous short-range and long-range monitoring.
• Has a maximum instrumented range of up to 36 NM and a 4.9-degree horizontal beamwidth.
• Supports radar rotation speeds up to 60 RPM.
• Supports MARPA tracking of up to 10 targets when compatible heading and position data are available.
• Operates from 12V or 24V DC, uses approximately 20W transmitting and 7W in standby, weighs approximately 5.9 kg, and has IPX6 protection.

Radar Integration

The HALO20+ requires a compatible Lowrance multifunction display and Ethernet radar connection for operation. NMEA 2000 can provide heading, GPS, AIS, autopilot, and other compatible sensor information, but radar video and control use Ethernet rather than NMEA 2000. Confirm the display family, software version, available Ethernet port, required adapter, and network configuration before purchase.

MARPA, radar overlay, and advanced target-tracking functions require compatible heading and position sources where applicable. VelocityTrack Doppler can help highlight moving targets, but results depend on scanner settings, target motion, weather, sea conditions, and clutter management. Radar is a navigation aid and does not replace a proper lookout, safe speed, official charts, local notices, or collision-regulation compliance.

Installation Considerations

Mount the 20-inch radome on a rigid platform with a clear rotating area and practical height above the waterline. Align the scanner parallel to the waterline, keep it clear of masts, antennas, lights, exhaust, rigging, and crew traffic, and maintain manufacturer-specified personnel safe distance and compass-safe distance. Verify the five-meter cable reaches without extensions, sharp bends, chafe, heat exposure, or interference. Radar installation and commissioning should be completed by a qualified marine-electronics technician.

Warranty and Saltwater Care

Lowrance warranty coverage varies by region, distributor, product registration, installation method, and intended use. Confirm local warranty terms, exclusions, registration requirements, and available service support before purchase.

The radome is designed for marine use and has IPX6 water-ingress protection, but this is not a guarantee against saltwater corrosion. Rinse salt spray with fresh water where appropriate, avoid direct high-pressure water at cable connections, inspect the radome base, mounting hardware, cable glands, connectors, and mounting platform regularly, and use compatible marine-grade fasteners and isolation practices to reduce galvanic-corrosion risk.

Before Ordering

Confirm compatible Lowrance MFD support, available Ethernet radar connection, suitability of the included five-meter cable route, 12V or 24V supply, suitable radar mount, clear 20-inch scanner rotation area, mounting height, personnel and compass-safe-distance requirements, heading and GPS source for MARPA or overlay, software compatibility, optional AIS integration, and qualified installation requirements before purchase.
