KHANN‑ONE is a compact, rugged multi‑band drone countermeasure system integrating 8 programmable bands (AFFANG‑ONE) with high‑gain helix antennas on a precision pan‑and‑tilt unit. Each exciter drives directionalantennas to deliver concentrated jamming energy or coordinated 360° airspace denial. It supports networked operation and can integrate with radar, RF detection and EO systems for real‑time cueing.
