【Main feature】
ANT-GL12 is a set of GPS L1 & L2 and GLONASS G1 & G2 dual-band double system measurement antenna, can be widely used in geodesy, bridge construction, marine surveying, underwater topography measurement etc.
The antenna using multi feedpoint design, ensure the antenna phase center and the geometric center of the coincidence, improve the accuracy of measurement. Built-in low noise amplifier module, through the multi-stage filter to eliminate interference signal ,ensure the normal work in harsh electromagnetic environment.
