Raymarine Magnum 4 Array

Description

The Raymarine Magnum 4ft open array antenna increases radar target tracking when long-range commercial craft cruise open offshore waters. Severe maritime clutter often hides small targets, creating immediate navigational navigation blockouts. Installing this high performance radar component delivers narrow horizontal beamwidth focus, allowing vessel captains maintain total situational awareness during rough sea transit operations safely.

This high performance radar component features a rugged 51.7-inch fiberglass shell optimized for premium exterior mast placements. Unlike small radome housings that blur close azimuth lines, this open array antenna delivers an ultra-sharp 1.85-degree horizontal beamwidth. The exterior shell achieves complete weather protection. This watertight barrier fully seals the interior arrays from heavy sea spray, making long-range target tracking highly effective over years of deep ocean deck operation.

Key Features of Raymarine Magnum 4ft Open Array Antenna

• The integrated high-stability array configuration ensures optimal signal balance. This structure minimizes physical wind loading, allowing for reliable mechanical performance during high-speed vessel transits.
• The top interface provides high-efficiency radar antenna component transmission. This precision-built electrical junction channels high-power pulses smoothly, preventing microwave energy loss.
• Features a tight 1.85-degree horizontal beamwidth paired with a wide 25-degree vertical beamwidth array. This layout provides exceptional target extraction close to the hull while maintaining tracking during heavy rolling.
• Designed for full hardware cross-compatibility with Raymarine Magnum 4kW and 12kW pedestals, enabling marine installers to upgrade or swap radiator elements safely without changing the transmitter base hub.

Why Choose This Radar over Generic Alternatives

Upgrading to the genuine Raymarine Magnum 4ft open array antenna is essential for achieving elite target separation over long distances. Unlike generic replacement whips with sloppy internal tolerances that introduce target blur, this high performance radar component provides a razor-sharp 1.85-degree beamwidth. It perfectly matches existing Magnum 4kW and 12kW pedestal configurations, protecting commercial operators from unexpected radar display blackouts safely.

Application & Limitations

This 4ft open array antenna excels as a dedicated radar upgrade on medium center consoles, sportfishers, and coastal cruising boats. However, because it features an extended length of 51.7 inches (1313mm), it requires a rigid structural mast or unreinforced arch placement to handle crosswinds. Additionally, since this is an antenna component only, it requires a compatible Magnum pedestal core to transmit signals.
