I'm trying to find it online for you. My group at Intel was researching content delivery via OTA HD. We set up some computers with HD cards and these RCA antennas at homes around Hillsboro, Portland, and Gresham (Hillsboro and Gresham are roughly equidistant from downtown Portland). They worked quite well. It's just a small black "squared loop" antenna. I'll keep looking. I'm sure they are still out there.
