The Battelle DroneDefender utilizes radio waves to neutralize in-flight Drones and force them to land or hover or return to its point of origin. Video Demonstration You can watch the video given below to know how the DroneDefender works. It shows how the weapon is able to stop a drone in its tracks and cause it to land. The DroneDefender weighs less than 5 kilograms and can disable a hostile drone within a 400-meter radius. How does DroneDefender Work? As soon as the trigger is pulled, DroneDefender emits radio pulses that interrupt the communications system
