Description

The Simrad HALO 4 Foot Open Array Radar Antenna Only is a replacement radiator bar for compatible Simrad HALO open-array radar pedestals. This four-foot antenna is not a complete radar system: it does not include a pedestal, transmitter, radar cable, chartplotter, power supply, mounting platform, heading sensor, or GPS source. When fitted to a compatible HALO pedestal, the four-foot array provides the antenna beam pattern for the completed radar scanner.

The 4 ft array provides an approximately 1.8-degree horizontal beamwidth and 22-degree vertical beamwidth. Radar output power, instrumented range, rotation speed, VelocityTrack Doppler capability, Bird Mode, MARPA performance, and target-tracking functions depend on the paired HALO pedestal and compatible Simrad display. Confirm exact pedestal compatibility and attachment hardware before purchase.

Key Specifications

Four-foot Simrad HALO open-array radar antenna radiator only.
Requires a separately selected compatible Simrad HALO radar pedestal.
Provides approximately 1.8-degree horizontal and 22-degree vertical beamwidth when paired with the appropriate pedestal.
Measures approximately four feet in length and weighs approximately 5.1 kg as an array-only component.
Receives scanner drive and operating power from the matching HALO pedestal.
Does not include radar transmitter, pedestal, power cable, Ethernet cable, chartplotter, radar mount, or heading sensor.
Radar range, transmitter power, rotation speed, Doppler functions, and tracking features depend on the paired pedestal model.
Requires a rigid radar platform with complete four-foot array rotation clearance and appropriate wind-load capacity.

Radar Integration

This antenna must be paired with a compatible Simrad HALO open-array pedestal and supported Simrad MFD connected through Ethernet for radar video and scanner control. NMEA 2000 can provide compatible GPS, heading, AIS, autopilot, and sensor data, but it does not carry radar video.

MARPA, radar overlay, VelocityTrack Doppler, Bird Mode, and target-tracking functions depend on the paired radar pedestal, display software, heading source, GPS data, and complete system configuration. Radar is a navigation aid and does not replace a proper lookout, safe speed, official charts, local notices, or collision-regulation compliance.

Installation Considerations

Install the complete pedestal-and-array system on a rigid level platform with sufficient strength and full open-array rotation clearance. Position it at a practical height above the waterline, align it parallel to the waterline, and keep it clear of crew, masts, rigging, antennas, lights, exhaust, and other obstructions. Maintain manufacturer-specified personnel safe distance and compass-safe distance for the complete radar system. Radar installation and commissioning should be completed by a qualified marine-electronics technician.

Warranty and Saltwater Care

Simrad warranty coverage varies by region, distributor, proof of purchase, product registration, installation method, and intended use. Confirm local warranty terms, exclusions, and service requirements before purchase.

The array is designed for marine exposure, but long-term saltwater durability depends on correct mounting, drainage, compatible fasteners, regular inspection, and manufacturer-approved maintenance. Rinse salt deposits with fresh water where appropriate, inspect the radiator, pedestal joint, fasteners, and mounting platform regularly, and use compatible marine-grade hardware plus isolation methods to reduce galvanic-corrosion risk.

Before Ordering

Confirm the exact compatible Simrad HALO pedestal, supported Simrad MFD, Ethernet radar network, antenna attachment hardware, four-foot rotation clearance, platform strength, wind-load requirement, mounting height, personnel and compass-safe-distance requirements, heading and GPS source for ARPA or radar overlay, required radar cable, and qualified installation requirements before purchase.
