The Raymarine Magnum 4-Foot Open Array (Antenna ONLY) is the individual replacement or custom-configuration antenna bar component for the Magnum radar series.

While the physical antenna bar itself is identical whether paired with a 4kW or 12kW system, mounting this 4-foot bar onto a 12kW Magnum Pedestal (E70487) unlocks the radar system’s maximum range and signal penetration capabilities.

Key Performance Advantages (12kW Pair)

• High-Power Target Penetration: Backed by the 12kW pedestal’s massive pulse energy, this antenna can cut through heavy downpours, dense fog, and sea clutter to clearly resolve small, distant, or weak targets.

• Maximum Detection Range: Unlocks an operational range scale of up to 96 nautical miles, giving offshore operators early visibility for blue-water crossings, landfalls, and weather systems.

• Enhanced Beam Sharpening: Features a 1.85° nominal horizontal beamwidth. When paired with the Magnum pedestal’s digital processing, Raymarine’s beam reduction narrows the effective bearing resolution to less than 1° for map-like coastal rendering.

• Superior Bird Mode: Optimized to automatically isolate and tune into low-flying flocks of sea birds up to 10 nautical miles away, helping tournament anglers trace active baitfish schools.
