Furuno 4kW 24" Dome f/1835 Radar — Product description
Enhance Your Furuno 1835 Radar with the Reliable 4kW 24" Radome Replacement
Upgrade or replace the antenna dome on your Furuno 1835 radar system with this precision-engineered 24-inch radome assembly. Designed exclusively for marine environments, it delivers consistent performance in spotting targets up to 36 nautical miles away, helping you navigate fog, rain, and low visibility with confidence. Boaters and professionals alike trust this radome for its rugged construction that withstands harsh saltwater exposure while maintaining sharp radar returns.
Unlike generic antennas, this Furuno-specific unit integrates seamlessly, restoring your radar's full capabilities without compatibility headaches. Its 4kW output power punches through clutter like rain and sea clutter, providing clearer images on your 1835 display for safer voyages.
Key Features and Performance Advantages
- Compact 24-Inch Dome Design: Sleek profile reduces wind resistance and fits neatly on masts or arches, ideal for sailboats, power yachts, and fishing vessels.
- High-Power 4kW Transceiver: Boosts detection range and resolution, excelling in identifying small targets like buoys or debris from afar.
- Narrow 3.9° Horizontal Beam Width: Offers superior target separation, minimizing false echoes and sharpening your radar picture for precise navigation.
- Weatherproof Build: Sealed against moisture and corrosion, ensuring longevity in demanding offshore conditions.
- Plug-and-Play Compatibility: Direct fit for the Furuno 1835, minimizing downtime during replacement.
Why Choose This Radome for Your Vessel?
Marine radars take a beating from constant UV exposure, salt spray, and impacts. When your original dome cracks, fogs, or loses sensitivity, signal quality drops, compromising safety. This replacement restores peak performance, with advanced materials that resist yellowing and maintain transparency for optimal signal transmission. Skip the guesswork—it's the exact match engineered for the 1835 model, supporting features like MARPA target tracking and anti-clutter processing.
Users report noticeable improvements in echo clarity during heavy weather, making it a smart investment for commercial operators, live-aboard cruisers, and weekend anglers who prioritize reliability over cost.

Installation Tips for Smooth Radar Operation
Mount the radome at least 8 feet above the waterline to avoid sea clutter interference, and ensure a clear 360-degree view unobstructed by masts or rigging. Basic tools suffice for swapping it out—disconnect power, remove the old dome, align the new transceiver, and secure cables. Always ground the system properly to prevent noise. For best results, calibrate your 1835 display post-installation to fine-tune gain and sea clutter settings.
Regular maintenance like rinsing with fresh water after use extends its life, keeping radar echoes crisp season after season.
