Sokkia offered a new antenna for the Axis3 L1 DGPS system. The new model replaces the existing one and is included with each new purchase of the complete Axis3 system. The new antenna is lightweight (1.1 lbs) and features a bold, rugged design, standard 1-14-UNS mounting thread for convenient installation, a wide range of input voltages and a shock-resistant exterior bumper. It is compatible with Beacon, WAAS and OmniSTAR corrections.
