Uh, the standard Winegard wall plate is NOT signal meter, it has inputs for Cable, And OTA, and outputs (one or two) on the back for the remote TV(s) and one on the front usually for the MAIN TV
The Sensar Pro has Two inputs and Two outputs (Same as the standard switch/power supply) but all are on the back and all are clearly labeled.
That said, I do not use the cable in on mine I have added a couple of down line splitters though. Originally each output ran direct to a digital converter, But as I improved things I ran one to the matrix switch and the other to a splitter, I can now do TV magic,
