4’ AIS 4.5dBi Marine Antenna (no cable)
To ease installation and antenna removal, DAI’s 1100 series antennas feature a quick lock system that eliminates cable twisting and allows the antenna to be removed. Use with an existing or custom 50 ohm cable run that will not twist when secured in the stainless steel collet ferrule.
The powerful brass radiators provide a low VSWR less than 1.5:1.0 from 159-164 MHz making it compatible with the most sensitive AIS transponder. Features include an SO-239 connector at antenna’s base and stainless steel 1″x14 double female ferrule. Ideal for use on commercial and recreational boats.
