I have a hdtv compatible or monitor. It still needs something for HDTV. Dish rep told me that due to my having a HDTV box which I get about 25 HD channels from Dish, I just need an hd antenna and can run it through the receiver and get HD locals plus the .1 and .2 channels etc. Went to a tv shop today and they insist I need a $400 tuner in order to get HD locals. I don't know who is right and I dont know who to trust. I live in Indianapolis and would like to get the Indy locals plus maybe Lafayette, Terre Haute etc. if possible. Any help would be appreciated.
