I want to use an OTA HD antenna...

I'll have two Sony XBR Wega's(a 40" and 36").

The 1080 PPV is upsampled but not a true virgin 1080P signal as with most HD content on Sat and to lesser extent cable the lie is in the details.

I use one of these DB4 Multi Directional HDTV Antenna. Search for it on Amazon. Just this weekend I unhooked my cable and had this antenna in the attic. I had RG6 coax run from the attic to the crawlspace. I ran this to my TV. Good results. I dropped cable Monday morning saving $100 month now. But you need a TV with a digital tuner. Otherwise you need some kind of box. I'm feeling real good right now about the savings. Time Warner raised their price by about 8% starting Jan 1st.

HD is UHF. So, Radio Shack U-75R is perfect, and at $29 it's cheap.

Much better than "high tech" but smaller antennas. I installed it inside my attic, works like a champ, picks up channels from far away, no problems. Run the coax straight into your TV if it has an HD tuner, or your external HD tuner box.
