Digital Antenna Automatic Identification System Antenna (MPN: 876-SW)

High-performance AIS antenna designed for commercial vessel compliance.

The Digital Antenna Automatic Identification System (AIS) Antenna is engineered to meet the stringent requirements of the USCG for commercial vessels. With a length of 4 feet and a 1 inch to 14 threaded base mount, this antenna is designed for compatibility with all AIS transponders. It features a low 1.5:1.0 SWR ratio across the 159 to 162 MHz frequency range, ensuring optimal performance and reliability in marine environments.

Constructed with powerful brass radiators and soldered connections, the antenna provides a gain of 4.5 dB, enhancing signal strength and clarity. The high gloss urethane finish not only adds to its aesthetic appeal but also contributes to its durability against harsh marine conditions. The inclusion of a 316 stainless steel double female ferrule ensures a robust and corrosion-resistant connection.

Installation is simplified with the factory-attached mini-UHF female connector and PL-259 adapter, allowing for quick and easy setup without the need for soldering. Each antenna is meticulously assembled, tested, and tuned by hand in the USA, guaranteeing maximum performance and quality for users in the maritime industry.
