Product Detail

ZD-KXAT170_8B1L1E1 is a high-performance 8-channel CRPA anti-jamming protected antenna, supporting reception, down-conversion, filtering and processing of BDS B1, GPS L1 and GAL E1 multi-system satellite signals. It provides 7-direction anti-jamming capability with single-direction suppression ≥110dB and 7-direction ≥85dB, effectively defending against broadband, narrowband, sweep, pulse and other abnormal electromagnetic interferences.

The antenna adopts IP65 protection and lightweight magnesium alloy structure, with an operating temperature range of -45℃ to +70℃, wide voltage input 12V~32V, power consumption ≤20W, weight ≤900g, MTBF≥5000 hours and continuous working time over 24 hours. Optional high-precision positioning and anti-spoofing functions are available. Designed with SMA RF interface and J30J-9 power interface, it is suitable for vehicle-borne, airborne and other high-reliability positioning scenarios, meeting high-precision and high-stable navigation and positioning requirements in complex electromagnetic environments.
