Actually, there are a few stations using VHF.
We have two, one on VHF-L and one on VHF-H

If you switch from standard to HDTV, the TV is more than likely switching to
a UHF channel, assuming your TV has both the ATSC and NTSC tuners. IF you
have a separate HDTV converter box, then you are switching the inputs of the
TV and the converter box is putting the channel number on the screen. The
confusing part is that the channel number comes from the information sent by
the station. For example, here in Colorado, channel 9 broadcasts HDTV on
UHF ch 16. But when you tune to HDTV, the channel number on the screen
still says 9. That is suppose to prevent confusion by the customer. But
you need to be aware of that. I believe all HDTV transmitions are on UHF,
at least for now. Any good UHF antenna will work but it appears digital
reception is more directional than analog. John.
