In practice, jamming of wide area is not a solved problem. It is easy to jam GPS because its signal is already weak, or a cell phone in a city, but it is very difficult to jam a drone in the sky which have a line-of sight to the antenna or a retranslation drone. Also all modern cheap drones have a way to switch frequencies if one gets jammed, and jamming all frequencies is also very very difficult.
You either need to have a very big powerful machinery - which is very easy to detect location of and send a HIMARS rocket. Or a huge number of smaller devices, which is impractical as you don't have power in trenches.
So in practice, drone jamming is only effective in the last 100-200 meters from the target (if it is a vehicle with power source) which doesn't really matters for surveillance drones as they do their job from the distance.
> Civilian radios are easily jammed.
In theory, in practice on the battlefield, when drones can switch frequencies on the go - very very difficult with the exception of the last hundred meters.
Because of this, modern killer drones now have a primitive "AI" to lock on the target on the last meters of approach.
