Ok, I just bought this house and the previous owners left the Direct TV dish installed as well as the OTA antenae and it has coax cable coming out of the wall. Since my tv is HD ready only and no turner built in, would I need to buy a turner or just plug it into the back of my tv to watch local HD channels free? Or would I simply have to call Direct TV and get their service with HD receiver to use OTA?
