The DroneDefender doesn’t make a cool sound when you pull the trigger, though, so I don’t like it. From Make : In a press release from Battelle, the gun is stated to use “radio control frequency disruption technologies to safely stop drones in the air, before they can pose a threat to military or civilian safety.” A video accompanying the post describes that it operates on standard GPS and ISM radio bands, allowing for it to interference with commercial UAV signals. Reportedly, the DroneDefender can hit objects up to 400 meters with an effective cone diameter of 30°. This is about as far as Battelle goes with the technical details, so the actual frequency ranges of the rifle still remain unknown.
