Shakespeare 396-1AIS Antenna For AIS Systems

The Shakespeare 396-1AIS Antenna For AIS Systems is purpose-built for mariners and vessel operators who require reliable automatic identification system reception and transmission. AIS technology is essential for modern maritime safety, collision avoidance, and regulatory compliance, making a dedicated, high-performance antenna critical to system performance. This commercial-grade antenna has been engineered specifically to handle the broader bandwidth demands of contemporary AIS transceivers, ensuring consistent signal clarity and range in demanding marine environments.

At 4 feet (1.21 meters) in length, the Shakespeare 396-1AIS delivers a 3dB broadband VHF response optimized for AIS frequency bands. The antenna employs a center-fed, half-wave coaxial sleeve design, a proven configuration that maximizes radiation efficiency and minimizes signal loss over the typical installation heights found on recreational and commercial vessels. This architecture provides superior bandwidth characteristics compared to narrowband antennas, allowing it to handle multiple AIS channels simultaneously without performance degradation. The mast mounting sleeve construction offers secure, reliable installation on standard marine antenna mounts while maintaining mechanical integrity in saltwater and high-wind conditions.

This antenna is ideal for boat owners upgrading existing VHF systems or installing new AIS capabilities on vessels of all sizes. The 396-1AIS works seamlessly with major AIS transceiver brands and integrates directly into existing marine electronics networks. Installation typically requires standard coaxial cable, a through-deck connector, and mast or rail-mounting hardware. Its commercial-grade construction ensures multi-year reliability in harsh marine conditions, making it a trusted choice for both saltwater cruising and coastal operations.
