Manufacturer Part Number (MPN)
E70491
Marine Electronics Specialist Insight: The Magnum 6 Array (MPN E70491) is the ultimate tool for serious offshore scouting. With a massive 6-foot span, it provides the narrowest horizontal beam width in the Magnum family (~1.15°). This translates to unmatched target separation and long-range clarity. When your mission is finding distant birds or navigating complex deep-water environments, the 6-foot array offers a level of precision that smaller antennas simply cannot match.
The Professional Standard for Long-Range Radar
The Raymarine Magnum 6 Open Array (MPN: E70491) is engineered for large offshore vessels, sportfishers, and commercial craft. As the largest antenna option for the Magnum series, this 6-foot array maximizes the performance of your radar pedestal. By utilizing a significantly tighter horizontal beam, it allows you to distinguish between two closely spaced targets—such as a navigation buoy and a small vessel—at much greater distances than smaller arrays or radomes.
Optimized for use with Raymarine’s **Axiom® and Axiom Pro** displays, the E70491 excels in Bird Mode. Its large aperture allows it to detect the faint radar returns of feeding birds at extreme ranges, giving you a competitive edge in the tournament circuit. Despite its size, the array features a sleek, low-drag profile designed to minimize wind loading and maintain vessel stability in heavy sea states.

Magnum 6 Array Elite Performance:
- Pinpoint Target Resolution: The 1.15° beam width provides the sharpest radar return available in the Magnum series.
- Unmatched Bird Mode Clarity: Specifically designed to locate feeding activity miles before it's visible on the horizon.
- Beam Sharpening Ready: When paired with an Axiom MFD, digital processing further narrows the beam for sub-degree clarity.
- Extreme Range Capability: Maximizes the range scale of the 12kW pedestal (up to 96NM) by providing a more powerful and directed pulse.
- Professional Offshore Profile: Adds a command-center aesthetic and tournament-grade utility to any offshore hardtop.
Frequently Asked Questions
1. Does this include the pedestal motor?
No, MPN E70491 is the 6-foot antenna array only. To create a working radar system, this must be paired with a Raymarine Magnum Pedestal (E70484 or E70487).
2. Is a 6-foot array too big for my 30-foot boat?
Typically, 6-foot arrays are recommended for boats 40 feet and larger due to their physical footprint and wind load. For vessels under 40 feet, the 4-foot Magnum (E70490) usually offers the best balance of performance and aesthetics.
