I have a projector that will display downconverted HDTV, and we have an over-the-air HD CBS affiliate here in town. What do I need to get the signal displayed on my projector for the Super Bowl? I assume I need some sort of tuner, and an antenna. Is there any product that is both an antenna and a tuner? How much money would I have to spend to get this done? Thanks for any input and I apologize if this has been discussed alot. I did not see it on the first few pages and my connection is too slow to search today.
