DroneGun Tactical is a jammer that blocks video transmission back to the drone operator and appears to also disrupt the GPS/GLONASS signal. This will cause most drones to either set down where they are or return to where they took off from. While DroneGun is illegal to use in the U.S., the result shouldn’t cause any injury to the drone or people around it because it doesn’t make it fall out of the sky, just initiate it’s safety protocols to land. It has an effective range up to 1 km, weighs 15 lbs. and includes two batteries. Pretty cool anti-drone measure. But…it’s also a pretty serious RF jammer, which is probably why the government doesn’t want you to own one. Thus, there’s no word on pricing. Just hope for now.
