Description
Raymarine 4kW Magnum Radar with 4-Foot Open Array & 15M Cable
Bridging the gap between recreational radar and commercial performance, the Raymarine 4kW Magnum Radar delivers enhanced target tracking and long-range power. This 4-foot open array system is engineered for American offshore yachts and commercial workboats that require high-definition imaging up to 72 nautical miles. For the USA captain, the Magnum radar features an advanced “Bird Mode” that identifies the signature of sea birds above baitfish schools, providing a tactical advantage for tournament fishing in the canyons or the open Pacific.
The Magnum series incorporates Raymarine’s beam-sharpening technology to deliver sub-degree horizontal resolution, ensuring that small targets remain visible even when adjacent to large landmasses or vessels. The included 15-meter heavy-duty cable simplifies the installation on large towers or masts. With its rugged construction and professional-grade performance, this 4kW system offers the American maritime market a dependable and high-power radar hub for serious coastal and offshore missions.

Common Questions for Raymarine 4kW Magnum
The 4kW Magnum needs a stable power supply meeting minimum marine cranking amps to handle the magnetron's peak transmission bursts. While it doesn't have a gallons per hour rate, the Raymarine Magnum Radar is energy-efficient, providing superior bird mode and long-range target tracking for offshore vessels.
A sportfishing boat or large cruiser is the optimal boat hull application for this 4-foot array, offering a narrow 1.85-degree beamwidth for precise separation. The Raymarine Magnum 4kW provides elite target imaging, allowing the Raymarine 4-Foot Open Array user to identify small debris or birds at significant distances.
Regularly check the sacrificial aluminum anode locations on your vessel to ensure the radar pedestal is not compromised by galvanic electrolysis. Maintaining the Raymarine Magnum 4kW involves freshwater rinsing of the array to prevent salt buildup, which ensures the antenna continues to rotate smoothly in harsh marine environments.
The included 15M cable is designed for larger vessels, but you should always use Genuine Raymarine Parts if an extension is required to maintain signal integrity. The Raymarine Magnum Antenna relies on high-quality shielded cabling to deliver the 48 RPM high-speed updates necessary for real-time navigation and collision avoidance.
The Magnum uses a sealed, grease-packed gearbox that does not have an FC-W engine oil capacity requirement or any need for seasonal fluid changes. This Raymarine 4kW Radar is engineered for low-maintenance reliability, using high-grade internal seals rather than oil baths to keep the mechanical components moving freely for years.
