I am in the market for an OTA antenna to pick up local New York channels in HD. I live 16 miles outside New York City. I called a guy who is going to install it for me and he told me I have to buy A Wineguard HD platinum antenna at $125. I think it is a little steep. What do I really need to get good HD local receotion? And how is the reception for New York HD? Can anyone help me?????
