Raymarine Quantum Radar – 18-Inch Wireless CHIRP Radome

Description

Add solid-state CHIRP radar to a compatible Raymarine system without the warm-up time of a traditional magnetron scanner. The Raymarine Quantum 18-inch Wireless CHIRP Radome combines a compact 20W dome, Wi-Fi or RayNet connectivity, and up to 24 NM of instrumented range for boaters monitoring traffic, shorelines, and weather during coastal runs or nighttime returns. Need a low-draw radar for a smaller boat or sailboat installation? Standard Quantum delivers 24 RPM scanning, MARPA support, and a 4.9° horizontal beam in a 12.3 lb radome.

Key Specifications

• Raymarine Quantum 18-inch wireless CHIRP pulse-compression radar radome.
• 20W solid-state CHIRP pulse-compression radar output.
• 18-inch enclosed radar dome.

• 24 RPM rotation speed.
• Supports MARPA tracking for up to 10 targets when connected to compatible heading and position sources.
• Standard Quantum model does not include Doppler target-color technology or dual-range operation.
• Wi-Fi or wired RayNet Ethernet connectivity.
• 10.8V–31.2V DC input; 17W operating draw, 7W standby draw, and 2W sleep-mode draw.
• IPX6 protection, 100-knot wind rating, and approximately 12.3 lb (5.6 kg) weight.

Integration

The Quantum requires a compatible Raymarine MFD for radar display and control. Radar video uses Wi-Fi or RayNet Ethernet, while SeaTalkng/NMEA 2000 can provide compatible GPS, heading, AIS, autopilot, and sensor data. MARPA and radar overlay require compatible position and heading data.

The 24 NM value is an instrumented range, not guaranteed real-world detection distance. Antenna height, target size, sea state, rain, weather, clutter, radar settings, and installation quality affect practical performance. Radar is a navigation aid and does not replace proper lookout, safe speed, official charts, or navigation-rule compliance.

Installation Notes

Install the radome on a rigid, level mount with clear rotation, practical height above the waterline, and minimal obstruction from antennas, lights, rigging, masts, exhaust, or other structures. Choose Wi-Fi or wired RayNet networking before routing cables, and protect power and network wiring from heat, chafe, standing water, high-current conductors, and moving equipment.

Use properly sized power wiring and recommended circuit protection. Follow Raymarine instructions for personnel safe distance, compass separation, mounting torque, grounding, and bearing alignment. Professional installation is recommended.

Before Ordering

Confirm compatible Raymarine MFD support, Wi-Fi versus RayNet connection method, 12V/24V power capacity, radar mount strength, 18-inch dome clearance, cable routing, and heading/GPS sources for MARPA or radar overlay before ordering.
