I use a HD OTA TUNER. Is that what you want?
I've got a question that I just can't find a reasonably priced answer to. I have a 58" commercial plasma display that only has 2 hdmi-in ports in the back of it. I have recently moved and now relying on the local digital antenna, which of course I can't hook up to my large plasma tv. So.. There lies the question, Where can I find a coaxial to hdmi converter or adapter?
