Overview
The GrAnt-G2T-JS-HPO GNSS antenna from JAVAD GNSS is a versatile, high-performance antenna. It can be mounted on flat surfaces with four screws or mounted on standard poles. The antenna cable can be connected via the standard TNC (N-type optional) connector on its side or routed through the center of the antenna for ultimate protection in harsh environments.
The GrAnt-G2T-JS-HPO can track GPS, Galileo, WAAS, EGNOS, MSAS, GAGAN, and QZSS signals.
J-Shield is the filter that protects GPS L1 and Galileo 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 this filter that protects GPS L2, GPS L5, 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 GNSS receivers’ performance.
The JS-HPO antenna option is characterized by an increased dynamic range of input in-band signals.
An optional ground plane can be purchased to increase multipath mitigation.
