Raymarine Magnum 4 Array
Fitting Magnum 4kW and 12kW radar pedestals on sportfisher hardtops, this Raymarine Magnum 4ft antenna sharpens beamwidth to 1.85 degrees across a 25-degree vertical span, delivering high-resolution target separation on an IPX6 frame at 10.4 lbs.
- 1.85-degree horizontal beamwidth resolves tight targets
- 25-degree vertical span maintains pitch tracking
- 10.4-lb weight minimizes masthead rolling sway
- Compatible with 4kW and 12kW pedestals
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.
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.
