AT500 Choke Ring Antenna
Other
Overview
The AT500 features a superior waterproof and dustproof design with an IP67 rating, and it can withstand drops from a height of 1 meter. The AT500 excels with its low noise amplifier, high gain, and sub-millimeter level phase center error, providing outstanding stability and repeatability. It can track all existing and planned satellite constellations, including GPS, GLONASS, BeiDou, BeiDou Global, Galileo, IRNSS, QZSS, SBAS and L-Band.
