KXAT168E_4B1L1E1G1 is a CRPA protection antenna designed for receiving, amplifying, down-converting, filtering, and processing signals across four frequencies: BDS B1, GPS L1, Galileo E1, and GLONASS G1. Powered by an 18V–32V supply, the unit consists of an antenna array, an RF module, and a processing module. It provides protection against abnormal electromagnetic signals from three directions, making it suitable for electromagnetic-sensitive scenarios reliant on high-precision positioning. It significantly enhances the stability of positioning equipment in complex electromagnetic environments.
