Raymarine RD424HD 24" 4kW HD Digital Radome – 10m Cable Included (T70169)

The Raymarine RD424HD with 10m cable (T70169) is the turnkey package of Raymarine’s top-of-the-line 24″ HD digital radome. Including the radome and a 10 m network cable, this kit is tailored for new installations on larger vessels that demand maximum radar performance. You’ll get the extended range and sharp detail of the 24″, 4kW HD scanner, along with the convenience of an out-of-the-box cable solution. From serious offshore cruisers to commercial workboats, this radar delivers open-array-like performance in a smaller footprint.

• Recommended Use: Designed for larger leisure and commercial vessels approximately 10–20 m (33–65 ft) in length. The RD424HD with 10m cable is often chosen for sportfishing boats, motor yachts, and patrol boats where long-range detection and fine target discrimination are crucial. The included 10m cable is typically sufficient to connect from a radar mast or cabin roof down to the main electronics hub on these boat sizes. If a longer run is needed, extension cables are available, but 10m covers many flybridge yacht scenarios.
• Ultimate Radar Clarity: The 24″ HD radome provides a significant step up in performance with its larger aperture. The narrower beamwidth means that two closely spaced targets at a distance appear separate rather than merging, which can be the difference between identifying a cluster of small boats vs. one large object on the horizon. Additionally, the larger antenna gathers more signal, improving return strength from distant storm cells or shoreline. Combined with Raymarine’s HD color signal processing, the RD424HD paints a vivid picture where land, weather, and moving targets are clearly distinguished. It’s an ideal choice for boaters who venture far offshore or in waters with heavy traffic, as it offers both range and precision.
• Advanced Features for Demanding Conditions: This radar adapts automatically as conditions change – calm or storm, day or night. Use the Weather (Bird) mode to amplify returns from rain squalls or feeding birds, helping you make informed navigation or fishing decisions. When navigating at high speeds or in confined areas, switch to short range and the scanner’s 48 RPM mode will ensure almost real-time updates on anything around you. Dual Range mode (with a compatible MFD like Axiom Pro) allows you to keep a watch on your immediate vicinity and far-off targets at the same time, essentially doubling your awareness. These sophisticated features mean the RD424HD isn’t just a sensor, but a critical navigation tool that you can rely on in all situations.
• Safety and Tracking: For collision avoidance, the radar’s MARPA function can track up to 10 potential targets. This can be especially useful on larger vessels that may operate with professional crew or advanced navigation systems – integrating MARPA data into your navigation workflow enhances safety during crossings or approaches. The system can trigger alarms if any tracked vessel poses a threat, giving the crew ample time to take corrective action. When combined with AIS data, you have both visual radar echoes and transponder information to identify ships, which is invaluable at night or in fog.
• Installation & Integration: The T70169 package comes with the standard 10m RayNet/Raymarine Digital Radar Cable, which carries both power and data, simplifying the wiring. Installation involves mounting the dome (which weighs ~10 kg) on a mast, arch, or platform – typical for boats of this class – and running the cable to your Raymarine display or switch. It’s truly plug-and-play with Raymarine’s LightHouse OS chartplotters: just connect and the system will recognize the radar. The RD424HD works seamlessly with multi-display networks; for example, you can view radar on multiple screens, or have one display on short range, another on long range. The radar’s compatibility across older and newer Raymarine systems protects your investment if you’re retrofitting – it can talk to legacy E-Series or C-Series Widescreen models, as well as new Axioms. In sum, the RD424HD 10m cable bundle provides an all-in-one solution to equip your vessel with a powerful, high-definition radar that rivals the performance of larger units, ensuring you have the information needed to navigate safely and efficiently.
