D-FENDER Series — Anti-Drone / Counter-UAV Systems

Counter Drone Systems

Description

D-FENDER is a family of high-power anti-drone jamming systems for defense, law enforcement and critical infrastructure protection. Models span lightweight tactical units and higher-power fixed/mobile systems, providing wideband disruption across ~0.4–5.8 GHz (including GNSS and ISM bands), directional antennas and outputs from ~100 W up to 230 W with stated mitigation ranges up to 2.5 km. Typical deployments include perimeter and convoy protection, tactical response, airport/aviation security, prisons, border security and VIP/government protection.
