Four-star MultiPatch High Precision GNSS antenna description:
 
The Four-Star MultiPatch GNSS active antenna has been meticulously engineered to deliver superior performance across GPS, GLONASS, Galileo, BeiDou, SBAS, QZSS, IRNSS, and L bands. This design ensures optimal accuracy and robust tracking in urban environments. With its uniform gain and near-perfect axial ratio, the antenna effectively mitigates multipath interference. The internal LNA offers outstanding out-of-band rejection, ensuring stability and reliability of GNSS signals. When employed for RTK applications on the base and/or the rover, it can achieve genuine centimeter-level accuracy. This antenna is designed for use with all-band GNSS modules.
