Description
The AJU-8130 is the eight-element workhorse: a 130 x 130 mm array with 110 dB single-jammer suppression, 100 dB on three jammers and 85 dB with seven jammers active at once. More elements mean more nulls can be placed at the same time, which is what separates an eight-element array from a four-element one in a dense jamming environment.
Key features
- Eight-element array, 130 x 130 x 23.7 mm, 500 g.
- Single-jammer J/S >= 110 dB, three >= 100 dB, seven >= 85 dB at -130 dBm.
- Up to seven simultaneous jammers from different directions.
- Built-in receiver plus protected RF output.
- DC 12-36 V, <= 14 W; IP65; -40 C to +70 C.
