GA-22

Optimized for Your AIS Transponder

High performance GPS antenna in IP67 enclosure

Overview

GA-22 is our new GPS antenna designed for AMEC AIS products. It can also be a replacement for other navigational devices.

The GPS antenna is engineered to meet rigorous demands of marine environment. It is tested with AMEC AIS transponders and has passed all relevant environmental tests. Its UV resistant enclosure is IP67 waterproof. The built-in high performance LNA (low noise amplifier) ensures excellent sensitivity.

GA-22 has 2 mounting options: pole mount and base mount. It has 10 meter RG174 cable that facilitates routing and installation
