ARKNAV GPS Tracking System

100% Real-time Visibility with Zero Blind Spots

A-111 Active GPS Antenna


As a leading manufacturer of GPS Antenna, we not only provide professional Active GPS Antenna, but also offer quality Waterproof GPS Antenna and Flange GPS Antenna.

Because of its unique 10 watt RF protection design, A-111 GPS Active Antenna is the most suitable GPS antenna for using in a server environment. A-111 GPS Active Antenna is equipped with 3 signal noise filters and 2-stage LNA (Low Noise Amplifier), which will provide the most accurate signal to GPS devices. Its wide-range power supply and short-circuit protection make A-111 GPS Active Antenna suitable for all kinds of GPS applications and will help prevent them from being damaged. Like all the other ARKNAV antennas,A-111 GPS Active Antenna is made with high quality double-shielding cable and silver coated conducting pin, and complies with RoHS directives.
