I was wondering if there is such a model of antenna that connects to the tv via component, HDMI, VGA, basically something other than coax. I ask because I have an Olevia 437V LCD with built-in tuner but can't receive any OTA HD broadcasts as of now. Auto channel search for "air" turns doesn't find anything, so I figure I need an antenna. Circuit City guy told me it would receive OTA HD broadcasts out of the box due to the built-in ATSC/NTSC tuner, but apparently not.
Anyway, I'm in a weird situation because I live on a college campus and my only option for cable is the university-provided cable service for things like espn, discovery, etc. However, they don't have HD service and don't plan on offering it anytime soon. So my one coax input on the 437V is already occupied and I want to hook up an antenna to another input to receive OTA HD broadcast of ABC, CBS, FOX, NBC, etc shows. Are such antennas even produced because I can't find one after searching various stores and the forums. What's my best option here?
