The GN-JS02-S1 is our entry-level CRPA antenna — a lightweight anti-jamming antenna and dedicated anti-jam GPS antenna built for weight-sensitive UAVs and light ground systems. As a precise CRPA anti-jammer, its two adaptive elements place nulls directly on a single interfering signal, keeping your GNSS position lock the moment a jammer switches on. Ruggedized for field and vehicle mounting.
