It would likely just jam comms, unless you can get it into the 10kw range or higher(risky and a magnet for A10 ammo). An omnidirectional antenna(beam antennae could work, if you know the direction of the drone that would be best as it's harder to triangulate) capable of handling 1500-3000w would be needed, considering the range of those rounds I am leaning towards 3000, some way to detect and isolate the signal frequency(hackrf? Rtlsdr?), and a broadbanded frequency modulator to focus your energy expenditure of a white noise generator. At that point you still have to isolate and disable the drone before your power supply runs dry, and they'll likely have someone within rifle range of it to shoot anyone who attempts to do so manually.
Judging by the antennae on the back of this thing, it operates somewhere in the ghz frequency range, which means line of sight transmission. 26 miles maximum due to the curvature of the earth, if the operator has elevation it could be easily double that. The transmitter cannot be all that powerful on that thing, due to it's size.
Unless of course it's relayed through a global hawk, which I wouldn't put past them. A few dozen of these dropped by parachute and run by a team a thousand miles away is possible with existing technology...
