Furuno RSB110-070 2.2kw 18" Radome

Navigating busy waterways or open ocean demands reliable detection of hazards, vessels, and weather patterns. The Furuno RSB110-070 steps in as a compact powerhouse, delivering sharp radar imagery from its 18-inch radome design. Engineered for seamless integration with Furuno's 1700 Series radars, this 2.2kW antenna enhances situational awareness on smaller boats where space and weight matter most.

Crafted with mariners in mind, it balances high performance with easy handling. At just 10.8 pounds, mounting it on t-tops, arches, or rails becomes straightforward, freeing up deck space for other gear. Its sleek profile minimizes wind resistance, ideal for trailered vessels or performance craft chasing speed.

Precision Performance in a Compact Package

The heart of any radar system lies in its antenna. With a tight 5.2-degree horizontal beam width, the RSB110-070 excels at target discrimination—separating close vessels or buoys from clutter. Expect a solid 24-nautical-mile range, capturing distant echoes while piercing rain or fog for clearer returns.

• Optimized Beam Width: Pinpoint accuracy helps avoid collisions in crowded marinas or during night runs.
• Extended Range: Spot commercial traffic or squalls well in advance, giving you time to adjust course.
• Durable Construction: Weatherproof radome shrugs off salt spray, UV exposure, and impacts common in harsh marine environments.

Unlike bulkier alternatives, this radome's low-profile dome reduces bird clutter and sea return, sharpening your display for critical moments like fishing in rough seas or coastal cruising.

Perfect Fit for Proven Systems

Directly compatible with Furuno's 1700 Series chartplotter-radars, it slots in as a drop-in upgrade or replacement. Boat owners upgrading from older 1723C or 1724C models find it restores full functionality without rewiring headaches.

Pair it with these units for enhanced features like MARPA target tracking or video plotting—tools that turn raw echoes into actionable intel. It's a smart choice for repowering aging setups, extending the life of reliable electronics.

Lightweight Design Meets Real-World Demands

Weighing only 10.8 lbs, installation feels effortless compared to heavier domes that strain mounts or complicate balance. This makes it a favorite for center consoles, walkarounds, and offshore skiffs where every ounce counts.

Performance shines in varied conditions: short-pulse mode for close-in detail during docking, or long-pulse for horizon scanning. Mariners report fewer false alarms near shorelines, thanks to Furuno's tuned signal processing.

Maintenance Tips for Peak Reliability

Keep it performing like new with simple routines. Wipe the dome exterior monthly with fresh water and a soft cloth to fend off salt buildup. Inspect cables seasonally for chafe, especially at swivel points. Avoid high-pressure washes directly on seams.

For troubleshooting, check power draw first—stable voltage prevents erratic sweeps. Furuno's engineering minimizes downtime, but proactive care ensures years of crisp returns.
