A smart, but unscrupulous, retailer could put the same antenna side by side on the shelf, one labeled "UHF/VHF Antenna" and the other one "Digital HDTV Antenna", mark the 2nd one at a higher price, and it would probably outsell the other !
I bought a simple Radio Shack U75R (UHF only) antenna years ago. In our old house, it was hung in the attic. At our new house, I put it on a metal pole, slipped that pole inside a buried pole for a Directv dish that I dismantled when we moved in. It's maybe 10' high and aimed at Cincinnati's stations about 30 miles away and I get them all. There is (1) VHF station that I don't get, of course. I'm less than 10 miles from Dayton's towers and get them full-strength even though I'm aimed almost 180º off-axis from them.
