Raymarine Quantum Q24C CHIRP Radome (Wired, 10m Power Cable)

The Raymarine Quantum Q24C is the wired-connection variant of the innovative Quantum radome, designed for users who want flexibility – the option of wireless connectivity or a robust wired link into the boat’s network. Physically, the Q24C is identical to the Q24W: an 18″ dome radar weighing about 5.6 kg, with a modern solid-state 20W transmitter. It uses the same CHIRP pulse compression to ensure clear radar images at short and long ranges (from ~5–6 m up to 24 nm) and gives the navigator a detailed picture of the vessel’s surroundings.

The primary difference is in connectivity: the Quantum Q24C features a port for a wired network connection (RayNet Ethernet), providing the ability to tie into the vessel’s Raymarine network via cable. Many skippers prefer a wired connection for absolute reliability and freedom from interference – the Q24C meets this need by allowing radar data to be delivered over a cable. At the same time, the model retains the Quantum series’ built-in Wi-Fi functionality, so the choice is entirely yours: you can run it wirelessly or wired, or even both (for instance, Wi-Fi to one display and cable to another backup display, if your setup allows). This unit is supplied with a 10 m power cable, but the data cable is sold separately according to the length needed (Raymarine offers 5 m, 10 m, 15 m, 25 m options). If you are upgrading from an older Raymarine radar, you can also use an adapter to mate the Quantum to your existing cabling, saving installation effort.

In terms of performance, the Q24C has all the strengths of the Quantum series. Minimal warm-up time – the unit essentially starts up and is ready to transmit in seconds, with no lengthy magnetron warm-up as in older radars. Instant wake from standby means you can keep the radar in sleep mode until needed, and it will begin scanning almost immediately – great for saving power on a sailboat. The Quantum Q24C uses auto gain and sea clutter settings optimized by CHIRP technology, so manual tweaking is minimized – radar returns are sharp and relatively noise-free under various sea states.

Use cases: This radome is excellent for sailing vessels, mid-sized motor yachts, fishing boats, and really any scenario where a small, lightweight yet powerful radar is needed. Sailors will appreciate the low weight aloft and the ability to have a reliable radar for offshore passages and night watches. Skippers of coastal cruising powerboats will gain timely information on hazards and other craft up to 24 nm around, greatly increasing safety in fog or darkness. For those navigating in high-traffic areas (such as near ports), the Quantum Q24C serves as an extra pair of eyes, simultaneously tracking up to 10 targets with MARPA (when paired with a heading sensor) to help prevent collisions.

Overall, the Raymarine Quantum Q24C offers an outstanding combination of modern radar technology and installation flexibility. Whether you choose to connect it over the air or with a cable, this radar will enhance your situational awareness and make your time on the water safer and more confident.
