Drones range from tiny short range scouts like AV Raven to huge Glogal Hawk. Besides target drones, all of them have a Ground Control Station component which is linked by radio telemetry to the aerial vehicule and sensors. Every radio signal can be jammed, altough this comes impractical because the jammed drone will fly away to a standby point away from your jamming source; and they can use several frequencies to communicate with their base. But to answer his question, yes all drones are affected by jamming but its definitely not easy. The military have had several decades of dealing with jamming and battlefield communications are pretty good.
No. The low end stuff is basically beefed first stuff. I personally know some drone guys.
The higher end stuff uses sat and spread spectrum. It's used because it's hard for nation states to jam it.
I know a fair amount about these systems having used them (granted not for 20 years). A full and complete answer to this question could result in a person putting ITAR restricted information online though. A UAS is a system of systems including communications systems, payload systems, flight control systems, the air vehicle itself, etc. The way that each of these systems works and interacts with the other systems varies depending on the particular UAS you are looking at.
I agree with that

That just means jamming is good* specifically for area denial*, which is important because the u.s. government isn't above drone bombing us citizens. Well I mean, it is 'above' doing that--it's kinda how drones work, but I digress. And worse, drones are super effective against pretty much all other means of conventional warfare, including insurgency, at least when the government can turn around and blame its mistakes, through a complicit media organ, on say, terrorism. So in a hypothetical showdown between the u.s. government (or western governments) and their own citizens, disabling their drones would be a priority above all others.
More generally, standby points are an exploitable weakness, assuming they're reused. Zone deny an area? Watch for the standby or drone rally point. Move into position. Repeat zone denial. Wait for the denied drones to arrive. Surface to air weaponry or anti-drone weaponry to take out the drone--hypothetically speaking.
Also, unless they're using HAM to bounce signals of the atmosphere, they'll have to remain within a very specific range of the drone, so if you know which frequency range the controlling unit is using (assuming it isn't satellite based), and you know some trig, and some spotters, the hypothetical militia and hypothetically use hypothetically improvised mortars IRA style to hypothetically send a friendly reminder to the hypothetical rogue military elements breaking their oaths, that it is unwise and unsafe to their individual persons to drone the citizenry, and that the citizenry do not like when their own police or military break their oaths to follow unlawful commands.
Hypothetically speaking.
I'm going to drop this subject
It's all a larp anyway. I comment, observe, and eat my popcorn while watching the news.
If anyone takes any of this shit seriously, they need their head checked.
