The drones operate using spread spectrum frequency hopping technology on the same frequencies as home wifi networks. They are designed to be far more resistant to interference than home wifi, so any jammer device would wipe out the internet for home users in a 5Km radius before it had any effect on a drone.
A shotgun at low level or a .50 calibre long range shot is the most effective counter measure against these devices if you must remove them from the air.
