Manufacturer Part Number (MPN)
E92143
Marine Electronics Specialist Insight: The RD424HD (MPN E92143) is the high-performance benchmark for mid-sized offshore vessels. By utilizing a larger 24-inch antenna, it delivers a tighter 3.9° horizontal beam width, which provides significantly better target separation than the smaller 18-inch models. This "No Cable" version is the ideal drop-in replacement for existing HD Digital installations or for custom builds where non-standard cable lengths are required.
Maximum Target Clarity in a Larger 24" Footprint
The Raymarine RD424HD (MPN: E92143) delivers a superior level of situational awareness for offshore cruising and technical fishing. With its powerful 4kW transmitter and high-definition digital processing, this radome cuts through sea clutter and heavy rain to reveal small, faint targets with 256-color detail. The larger 24-inch diameter allows for a narrower beam, ensuring that closely spaced targets—such as channel markers or vessels in a tight group—are displayed as distinct objects rather than a single mass.
This HD series radome supports Dual-Range mode, allowing you to simultaneously monitor the horizon for weather cells while tracking nearby navigational hazards on a split-screen display. Its High-Speed 48 RPM tracking provides lightning-fast target updates, which is essential for safely navigating at higher cruising speeds or tracking fast-moving surface targets.
