On our mini lite, we never have to switch the coax on the wall plate. As was mentioned above, we have "tv" and we have "Aux/Sat".
The outside inputs are "cable" and "aux/Sat". Cable goes to "TV" on the inside wall plate, and Sat goes to "Sat" inside on the wall plate. We have never disconnected the coax and moved it from "tv" to Sat". We simply click on the antenna booster and change the tv (in the menu) to "Air" and run the auto program
But it is certainly possible, with the crazy things you hear about from the factory, that my configuration differs from others
