Product Overview

The ZDAJ-4-B1-2 is a high-performance, multi-system GNSS anti-jamming antenna designed to provide reliable positioning and timing in complex electromagnetic environments. Supporting BeiDou BDS B1, GPS L1, Galileo E1, and GLONASS L5 signals, this antenna offers excellent anti-jamming and satellite receiving advantages.

The device can simultaneously deal with multiple types of jamming signals such as pulse, frequency sweep, spread spectrum matching spectrum, and more. The anti-jamming capability is ≥100 dB under a single simultaneous jammer and ≥90 dB when three simultaneous jammers are used, effectively covering the full range of 0°~360° and -90°~90° pitch angle. Its highly integrated hardware architecture, compact size (130 × 130 × 33 mm), low power consumption (≤20W), and lightweight design (≤600g) make it suitable for drones, vehicles, and various high-precision positioning systems.
