I have a TV that the f-connector coax attachment got broken off. Now there's no way to plug an antenna into the TV. It still has 2 sets of RCAs that work. What I'd like to do is attach my cable box to the TV through the RCAs. I do not have a VCR with that TV. Does anyone know of a Coax to RCA converter? I've seen loads of products that convert from RCA to Coax, but none that do the reverse. Thanks for any help you can give me.
