Overview
The RingAnt-G3T GNSS choke ring antenna from JAVAD GNSS is their GrAnt antenna mounted on a choke ring. The antenna cable can be connected via the standard TNC (N-type optional) connector on its side.
The RingAnt-G3T can track GPS, GLONASS, Galileo, BeiDou, WAAS, EGNOS, MSAS, GAGAN and QZSS signals.
J-Shield is the filter that protects GPS L1, Galileo L1, and GLONASS L1 bands. It brings in all the useful signals intact and rejects out-of-band signals with a slope of about 12 dB/Mhz.
Similarly, it is the filter that protects GPS L2, GPS L5, GLONASS L2, GLONASS L3, and Galileo L5 and has a slope of about 9 dB/MHz.
These filters have been extensively tested with five different innovative tests and prove that the filters also improve the performance of GNSS receivers.
