If you live close to a town where there are TV towers, even the cheapest little devices, even the flat mats you hang on the wall will work alright. If you live a little further out you might have to spend a little more money (typically about $30). You can get one of the amplified directional antennas with a motorized mount. They are a gaudy looking, cheaply made and designed to have a life span measured in months. Here is a link to the last that one I bought:

If you get a Digital Converter Box w/TV Recording, you can have your complete Redneck TIVO type experience without paying the cable companies a dime. You can even continue using your old TV.
It is the next best thing to VHS. Here is a link to the last one that I bought a couple of years ago.
