I live in a condo, so outdoor antennas are out. I'd like to test the various indoor antennas. (Suggestions are most welcome.) My question is this: Can I get a read on my ability to receive HDTV signals by connecting the various antennas and seeing how they receive OTA UHF signals? (In DC, HDTV is all UHF.) For instance, If I can receive PBS (26), UPN (20) and WB (50) will that tell me anything useful about my ability to get the digital broadcasts? I prefer not to buy a HDTV tuner until I know that I can use it and, to be honest, before Samsung's $399 comes out? Thanks for the help.
