Funny, I was going to ask the same exact question today.
Thanks!
I might state Stan's answer another way by saying the Sat cable runs from the exterior to the separate wall plate, period. You hook your Sat receiver to that plate. The CATV cable runs from the exterior to the wall plate with the antenna booster switch. The bedroom and outdoor cable outlets only get the antenna /CATV signal unless you rig up a connection between your Sat receiver and the other cables.
I hope I got that right.
