They are planning, but their HOME ‘Defense’ drones aren’t going to be all satellite controlled. Ground-air links and shorter ranges are going to be the norm. And, that is where they are vulnerable. RF saturation is a bitch.

I'm not an expert in this sort of thing, but I've often wondered if a simple spark-gap generator could spit out enough wide spectrum radio interference to jam up something like a drone, or even a patrol officer's radio.

Spark gap transmitters are notorious for their ability to interfere with RF. Mathematically, the Fourier transform of a true impulse is a never-ending frequency spectrum.

What does this mean in actual practice? An extremely short electrical radiated impulse (or facsimile thereof) is extremely broad banded in the RF spectrum. IOW, wide band RF interference.

That aside, there are other more simple means to defeat links like this with much, much more power.
