AIS Antennas
4' Length, 4.5dB Gain

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 Antennas 4.5 dB gain AIS antennas offer unsurpassed durability and performance compatible with all AIS transponders.
