I have a Roamio OTA. Up until about a month ago everything was fine but then my favorite channel (11.1) stopped working. I assumed it was my antenna because I originally bought a cheap piece of junk. I finally got around to ordering a new one and installed it last night. Same issue. 11.2 and 11.3 work just fine. The signal strength is about 70 which I know is below their recommendation but I would expect pixelation or maybe even sound with no picture but instead there’s just a black screen. If I put the exact same cable directly into the TV then that channel comes in great. I’m at a loss. Anyone have any tips?
