I'm using an HDTV antenna made by Terk, which gets both VHF and UHF
HD. It has a scary looking UHF antenna, then two rabbit ears for VHF.
When assembled, and with the whips down, it looks like the number 7.
There's a Philips HD antenna that has just the UHF element. For a
while, Radio Shack was selling an HD antenna that had two loops
mounted parallel to the table surface, unlike most antennas where the
loop is perpendicular. I have no idea if that was a UHF only antenna.

There's a Zenith antenna out there that's designed to work only on UHF but
people have found it's OK for channels 7-13 as well. Channels 2-6 are a
lost cause on that antenna, but there are very few DTV stations planning
on using those channels. (you should check before buying one though, and
make sure your city isn't one of the exceptions!)

In theory, the old UHF loops would always have worked better when bent
parallel to the table surface. All TV stations' signals have a
horizontally-polarized component - almost none (especially on UHF) have a
vertical component.

Experts are finding that the old-fashioned "bow-tie" antennas (with the
flat screen behind them) are the most effective DTV antennas. In theory
they're only good for UHF but people are reporting decent results on
channels 7-13 as well.
