T70408 – Magnum Radar 4kW with 4ft Antenna and 15m Cable

The Raymarine Magnum 4kW open-array radar is a high-performance solution engineered for extended range and superior target resolution in all conditions. Equipped with a 4-foot antenna array, it offers a maximum range of up to 72 nautical miles, giving captains ample time to spot land, weather cells, or vessel traffic well beyond the horizon. The 4ft antenna provides a horizontal beam width of approximately 1.85°, delivering sharp detail while maintaining a compact footprint ideal for smaller to mid-sized vessels. This all-in-one package includes the 4-foot antenna, the 4kW pedestal transceiver, a 15 m RayNet cable, and the VCM100 power module – everything needed for installation and integration. Built on proven magnetron radar technology trusted by the United States Coast Guard, the Magnum 4kW is designed with a rugged housing and an open array scanner that withstands harsh marine environments for years of reliable service.

What sets the Magnum 4kW apart is the suite of advanced features that enhance situational awareness. Bird Mode comes standard, automatically tuning the radar to detect seabird flocks up to 10 nm away with remarkable clarity – a huge advantage for offshore fishing, as birds often signal schools of fish below. The radar’s imaging is further refined by Raymarine’s beam sharpening technology, which yields an effective bearing resolution better than 1°. This means even small or closely spaced targets appear as separate blips, and coastal features are painted with near-photographic detail on your chartplotter display. For tracking moving targets, the Magnum provides best-in-class MARPA functionality: it can automatically acquire and track multiple targets, utilizing Raymarine’s Evolution 9-axis heading sensor for real-time accuracy in target plots. Coupled with the True Trails feature, every moving contact leaves a faint wake on the radar screen, allowing you to instantly discern the direction and history of other vessels – critical for safe decision-making when navigating in heavy traffic or low visibility. Additionally, when paired with Raymarine’s Axiom series MFDs running LightHouse 3, the Magnum supports real-time heading updates, meaning the radar image rotates fluidly as your boat turns without screen re-draw delays. The result is an uninterrupted, accurate radar picture even during sharp maneuvers.

The Magnum 4kW with 4ft array is an ideal radar for yachts and sport-fishing boats that demand professional-grade performance in a compact form. The 4-foot array offers an excellent balance between antenna size and resolution; it’s perfect for installations where a larger antenna might be impractical. (For those who require even greater resolution and range, the Magnum is also available with a 6-foot antenna, model T70410, which further narrows the beam to ~1.15° for enhanced target detail.) Magnum radars feature dual-range capability, enabling simultaneous monitoring of both short-range and long-range scales on split-screen. Seamless integration with Raymarine MFDs is ensured – the Magnum is the perfect companion for the award-winning AXIOM and AXIOM Pro series, catering to captains who refuse to compromise on their electronics. It’s also backward-compatible with many legacy Raymarine displays (including a-, c-, e-, eS-, and gS-Series), safeguarding your investment during upgrades. With the Magnum 4kW radar on board, you’ll experience greater confidence on the water – from navigating crowded harbor entrances in poor visibility to tracking distant storm cells and flocks of birds offshore, this radar delivers the range, clarity, and advanced features to keep you safe and informed on every voyage.
