If you use a surface wave transmission line with RF launcher cones on the ends you can send gigabits over a single 28 awg copper wire at very low loss from 100 MHz to ~10 GHz. The only problem is that the line has to be suspended and away from conductors.

madengr responded with a completely on topic link to a surface wave transmission line start-up. But it looks like that comment, and 2/3 of their other on-topic posts are getting grayed out [dead]. I don't think they know.

madngr: your account my be shadowbanned and only viewable by those like me that show dead posts.

Yeah, I did some EM simulations of that years ago when I read about it. Shame it never took off. The balloon tether is really cool.
