Does that fall under "All Other Weapons"?

For quickly hanging an antenna in a tree (or similar). I'm guessing it's for ham radio operators to improvise if they need to for some reason.

If things are that bad, I want to know how they're going to fill the reservoir...

There ain't going to be any air compressors that's for sure.

Plenty of systems holding Freon though.

Might make a decent propellant. Not very good pressure (and I'd be leery of tapping into a home or commercial system because some of those are very high pressure from what I understand), depending on the temperature, but it's dense and expands like crazy.

Standing pressure on a R-22 system is about 100psi. R-410 is considerably higher.

At that point we go back from "It's who you know" to "it's what you know".

It shoots a tennis ball with some fishing line up in trees. They then pull the wire antenna up using the fishing line. I thought it was just a tennis ball cannon.

These guys get all into it:

So just think of it as a "nerd gun". Check out the spinning reel on the end. I wonder if you could make one using a harpoon for carp fishing???
