Raymarine RD424HD 4kW Digital Radome Radar Dome

Description

The Raymarine RD424HD is a 24-inch, 4 kW HD Digital magnetron radar radome for compatible Raymarine multifunction displays. It uses a solid-state modulator to drive a magnetron transmitter and provides 256-color target presentation, adaptive digital receiver processing, Bird Mode, dual-range operation, scan averaging, and radar target tracking when used with compatible Raymarine display and sensor equipment. This radome is supplied without a radar cable.

The scanner provides a maximum instrumented range of 48 NM, 3.9-degree horizontal beamwidth, 25-degree vertical beamwidth, and rotation speeds of 24 RPM or 48 RPM with compatible displays. It requires 12V or 24V DC power and connection to a compatible Raymarine MFD through the required Digital Radar cable, crossover coupler, and SeaTalkhs or RayNet network arrangement. Actual target detection depends on mounting height, target size, weather, sea state, radar settings, and local conditions.

Key Specifications

• Twenty-four-inch Raymarine HD Digital magnetron radar radome.
• Provides 4 kW peak transmit power with a solid-state modulator driving a magnetron transmitter.
• Offers a maximum instrumented range of 48 NM and a minimum range of approximately 15 m.

• Supports 24 RPM operation and 48 RPM scanning with compatible Raymarine displays.
• Includes adaptive digital receiver processing, 256-color target presentation, Bird Mode, dual-range operation, scan averaging, and compatible MARPA support.
• Operates from 10.8V to 33V DC, uses approximately 60W transmitting and 25W standby power, weighs approximately 10 kg, and has IPX6 protection.
• Does not include the required Digital Radar cable, crossover coupler, RayNet or SeaTalkhs network connection, compatible MFD, radar mount, heading source, or GPS source.

Radar Integration

The RD424HD requires a compatible Raymarine multifunction display for radar control and video display. The scanner uses a Digital Radar cable and SeaTalkhs or RayNet Ethernet connection for radar data; SeaTalkng or NMEA 2000 can supply compatible GPS, heading, AIS, autopilot, and other sensor data but does not carry radar video.

MARPA target tracking and radar overlay require compatible heading and position sources where applicable. Bird Mode and dual-range operation depend on compatible display software and scanner 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

Mount the 24-inch radome on a rigid platform with clear scanner rotation, practical height above the waterline, and alignment parallel to the waterline. Keep it clear of crew, masts, rigging, antennas, lights, exhaust, and other obstructions. Maintain manufacturer-specified personnel safe distance and compass-safe distance. Select and route the required radar cable away from heat, chafe, bilge water, high-current wiring, and moving equipment. Radar installation and commissioning should be completed by a qualified marine-electronics technician.

Warranty and Saltwater Care

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

The radome is designed for marine exposure and has IPX6 water-ingress protection, but this does not guarantee immunity from saltwater corrosion. Rinse salt spray with fresh water where appropriate, avoid high-pressure water at the cable gland and seals, inspect the radome base, fasteners, cable connections, and mounting platform regularly, and use compatible marine-grade hardware plus approved isolation methods to reduce galvanic-corrosion risk.

Before Ordering

Confirm compatible Raymarine MFD support, required Digital Radar cable and crossover coupler, SeaTalkhs or RayNet Ethernet connection, 12V or 24V power supply, suitable radome mount, clear 24-inch scanner rotation area, mounting height, personnel and compass-safe-distance requirements, heading and GPS sources for MARPA or radar overlay, optional AIS integration, and qualified installation requirements before purchase.
