In conjunction with the USCG Automatic Identification System (AIS) requirements for commercial vessels, Digital Antenna created a series of 4' AIS antennas that meet the exacting AIS frequency requirements. Designed with a low 1.5:1.0 SWR ratio from 159-162 MHz, Digital Antenna's 4.5 dB gain AIS antennas offer unsurpassed durability and performance compatible with all AIS transponders.
Customers and installers love the 500 GOLD Series' easy installation connector system. The gold factory-attached mini-UHF female connector with PL-259 (UHF) adapter makes connecting to the AIS transponder easy, eliminating the need to solder connectors.
All of Digital antennas are made in the USA, assembled, tested and tuned by hand for maximum performance, quality and durability.
