Robin is looking to cut the cable and wants to use an over-the-air antenna to get live TV. Leo says that if she can get reception, then an antenna can take over for the satellite and she'll end up with a very nice, and more uncompressed HD broadcast. Leo advises going to AntennaWeb.org and see what she can get in her area based on her address. It'll also recommend the best antenna for her area.
Robin is also wondering what DVR she could use for it. Leo says a TIVO is a good option. Go over to WeakKnees.com. She'll still be paying someone for TIVO, though.
