I was curious if anyone has encountered a similar problem. I have a cheap Terk antenna in the attic to recieve several local HD feeds. It was hooked up and working perfectly fine. But last week I went to watch "Lost" on one of those channels, but I recieved no feed (picture or sound). My first assumption was that the antenna had somehow gotten unplugged or a cable became loose. I went up and checked and everything was fine, so I then tried to re-possition it, still nothing. I will get a good antenna once the rest of my roof gets done probably next year. But for now, is there anything I forgot to check or anything? has this happened to anyone else before? Its pretty mentally frustrating to not know what is wrong.
