Looks like my Winegard sensor is failing. Some of my close local channels are not coming in with the tv showing "No Signal". Tried cleaning the coax connections and trying another input to the switch ...
I just had to replace lots of my antenna system. Coax on three roof deteriorated to point that shielding was pretty much all exposed and after replacing found the amplification was no longer working. Had to replace with an equilivant of the box of many buttons. While I was at it I just went ahead and put in a 40 inch smart TV.
