HDTV via antenna and analog cable tv connection

What you're going to have to purchase is an Over The Air (OTA) receiver and a decent antenna to go along with it. The receiver will connect to the television via component video, HDMI, S-Video, or Composite. I suggest using either HDMI or component since they provide the most bandwidth (thicker cables are better). The OTA receiver will pick up all of your local digital stations but the HD content is "usually" only broadcasted during primetime hours (7pm-11pm). PBS transmits HD content throughout the day. When you're done with local stations just change your TV input back to your analog cable signal. I have this setup and it is pretty cool but i'm longing for more! I am tempted to get a dish but money is tight in New Orleans these days (Hurricane Katrina made life tough here). Hope this helps.
