talking to someone about direct tv systems, how they talk between HD boxes over the rg6 coax line one person said one part sends a signal and it travels down the center of the center coax conductor and another signal going the other way travels down the outer part of the conductor, the surface of the center wire.
but isnt the detail that the conductor is a transmission line that can be driven from different points?
like a steam pipe, you tap on it from the basement or 3rd floor and both hear it
