Combining cable and tv antenna signals

17 years ago

I have Time Warner cable which does not carry HD signals on their local channels. I want to install a TV antenna to get local channel HD reception on my HDTV. Is there any way to combine the cable & tv antenna signals in the attic, send the combined signal down the coax to the wall jack @ behind the tv and then split the signals to the HD DVR cable box and the tv? If so, what equipment would I need?

Not completely sure of this, but I tried the same thing last year and was told by TW it couldn't be done. They explained to use a diplexer, one signal would have to be analog and one would have to be digital. Again, I'm not sure this is correct, but I couldn't get it to work and that was the explanation I was given.
Hope that helps.
