TOKNAV TCA920 Choke Ring GNSS Antenna

TCA920 choke ring GNSS antenna for CORS, RTK base station and monitoring

TOKNAV TCA920 is a choke ring GNSS antenna for CORS reference stations, RTK base stations, deformation monitoring and high-precision receiving systems. Buyers can review signal support, multipath suppression, receiver pairing and antenna selection resources before deployment.

TCA920

2D Choke Ring Antenna

The TCA920 utilizes a traditional 2D design, covering multiple frequency points. With multipath suppression technology, it can mitigate the effect of multipath effect on measurement and positioning accuracy. This antenna is well-suited for applications in surveying, aviation, reference stations, government, and mechanical control, among others.
