Raymarine E22079 Long Arm Mast Head W/100'CABLE

The Raymarine E22079 Long Arm Mast Head with 100' Cable is a professional-grade marine electronics component designed for maritime surveillance, navigation, and tactical vessel operations. Built for law enforcement, military, and commercial maritime operators, this mast head unit extends sensor range and improves situational awareness from elevated positions on vessel structures. The extended cable run—100 feet—enables flexible system architecture on larger vessels or when sensor placement must be positioned far from command stations, a critical requirement in specialized maritime tactical operations where cable routing and antenna positioning directly impact electronic warfare and surveillance effectiveness.

Raymarine's long-arm mast head design features a robust construction rated for sustained marine environments, including salt spray, UV exposure, and vibration from vessel operation. The integrated 100-foot cable assembly eliminates the need for field termination and splicing, reducing points of failure and signal degradation common in field-modified installations. The extended arm geometry optimizes antenna pattern characteristics and reduces interaction with deck-level metallic structures that would otherwise degrade signal clarity. Weighing only 4 pounds, the E22079 maintains minimal topside weight distribution—a critical factor on high-speed interdiction or patrol vessels where mass aloft affects stability and fuel efficiency.

This mast head assembly is ideal for operators running integrated Raymarine marine electronics systems on patrol boats, coastal security vessels, and law enforcement craft requiring enhanced radar or communication array reach. Installation requires mounting to a suitable mast or antenna structure with proper grounding per marine electrical standards. The pre-assembled 100-foot cable harness connects directly to compatible Raymarine transducers and processing units, streamlining deployment and reducing installation time in operational environments. Proper cable strain relief and UV-rated conduit protection are essential during installation to ensure longevity in continuous maritime service.
