That and larger drone comms for russia I would guess are satellite based which is harder to jam and sadly out of budget for the Ukrainians.

That being said I wonder if you could control small drones over satellite or if that is a $900 solution to a 99 cent problem.

Satellite communications also has the issue of bigger form factor and larger power requirements. Not an issue for a predator drone, but your DJI isn't going to be using satellite comms any time soon.

The more promising areas are optical communications (but this has issues with fog and atmospheric attenuation), or directional antennas. Like, a yagi on a gimbal constantly pointed at the control station.
