The mainstream GN-JS04-S1 is a commercial-grade CRPA antenna and CRPA anti-jammer that adds two more elements for seven adaptive nulling directions and ≥110 dB rejection — the sweet spot for multi-threat environments where several interferers may be active at once. This anti-jamming antenna protects UAVs, autonomous systems, and critical infrastructure against high-power GNSS jamming and spoofing.
