I recon for ~$300 in parts your "typical hardware hacker" could build a rig that would focus 600W of microwave energy into a parabolic dish with reasonably tight beam. That shouldn't really affect anything but the drone.

If I was building a drone to do sabotage, I'd build a comms link around modulated NIR lasers targeted with mirrors rotated by microsteppers.

Did you see the article about optical links for micro sats?

I wonder if you could communicate with a drone from orbit (obviously in clear conditions).

*reckon

I thought you were saying you do reconnaissance for $300 before finishing the sentence.

Can't you just jam it with a very directional antenna?

You need to find where it is first and be able to track it.

Finding it doesn't seem hard, it really seemed to try to get as much attention as possible.

And without being able to command it or GPS it shouldn't be hard to track it either.

In theory it could be following waypoints (no command frequency) and using ultrasonic "sonar" to avoid things like trees at low level. That's pretty difficult to track, especially if you're on the ground in an area with a lot of trees.

Sure, but extremely unlikely.

That's why radar was invented.
