This drone gun knocks drones out of the sky gently, with radio waves

Drones are flying bundles of sensors and radio waves, sometimes put to nefarious purpose. In Iraq, the insurgent group ISIS put this combination to deadly effect, killing enemies and assembling a small aerial arsenal. Small, deadly drones used to kill are relatively new to battlefields, so companies are making new weapons to take drones down. The latest, from DroneShield, is the plainly-named "Dronegun." The company claims the weapon has a range of over a mile, and promises to immediately cease video transmission back to the drone operator.
