E70490
Marine Electronics Specialist Insight: The Magnum 4 Array (MPN E70490) is the tactical choice for mid-sized offshore vessels. Providing a 4-foot span, it offers a significantly tighter horizontal beam than any radome, ensuring superior target separation and long-range clarity. When paired with a Magnum pedestal, this array utilizes advanced beam sharpening to deliver a sub-degree effective beam width, allowing you to distinguish between small vessels and close-proximity navigation marks.
Precision Scanning: The 4-Foot Magnum Advantage
The Raymarine Magnum 4 Open Array (MPN: E70490) is designed for the captain who demands a professional-grade radar image without the massive footprint of a 6-foot array. This antenna is the critical component of the Magnum radar system, responsible for projecting and receiving the high-frequency pulses that define your situational awareness. Its 4-foot length provides the perfect balance between aerodynamic efficiency and the narrow horizontal beam width required for spotting distant birds and identifying tight-quarter targets.
Engineered for use with either 4kW or 12kW Magnum pedestals, this array excels in Bird Mode, helping offshore anglers locate feeding tuna and billfish by identifying bait balls miles before they are visible to the naked eye. Built to withstand the harshest oceanic environments, the E70490 features a sleek, low-drag profile that minimizes wind load on your T-top or hardtop.

Magnum 4 Array Performance:
- Ultra-Sharp Target Separation: The narrow horizontal beam allows you to see two distinct targets where other radars see one.
- Enhanced Bird Mode: Pair with a 12kW pedestal to maximize the array's ability to find bait-feeding activity at long distances.
- Beam Sharpening Technology: Digitally narrows the beam for Axiom users, providing a clarity typically found in much larger antennas.
- Heavy-Weather Resilience: Designed to penetrate heavy rain and sea clutter for safe navigation in all conditions.
- Professional Aesthetic: The sleek 4-foot open array adds a sophisticated tournament look to any vessel's profile.
Frequently Asked Questions
1. Does this product include the motor/pedestal?
No, MPN E70490 is the 4-foot antenna (array) only. It must be attached to a Raymarine Magnum Pedestal (E70484 or E70487) to function.
2. Can I use this with my older Raymarine SuperHD pedestal?
The E70490 is specifically optimized for the modern Magnum pedestal series. While physically similar to older arrays, for the best performance and "Beam Sharpening" features, pairing with a Magnum pedestal is required.
