There's only 3 components plus the TV, at least with my system. Winegard antenna, Winegard Booster (Photo I had attached) and the cable. I'm sorry, but either your TV has an issue or there's no channels in the area. (Unles you got a defective part?) Like I mentioned, I knew I had an issue, because where I park, I always had channels, and fortunately I have an additional TV that I use, so I don't drain the battery while boondocking. It's a small rechargeable 12 volt, so I knew it wasn't the TV since both were not getting a signal.
