coax if you run them parallel?

That's something I also had trouble getting my head around too. EMC expert Henry Ott, who retired many years ago from AT&T Bell Labs, was they guy who explained it to me. It has to do with the coupling between the center conductor and the shield of coax -- when current flows in the center, an equal current flows in the shield, and we're stuck with the loss of both of those currents.
