uhf ?

Bob-

It depends on where you are. There is a web site that has that
information, along with pointing information from your location. I just
can't recall the URL due to Old Age!

I think we all are experiencing the same problem with HDTV, regardless
of whether we have a converter box or an HD set. Unless you happen to
be close to the transmitter site(s), you probably need an outdoor
antenna, as others have suggested. I'm using a simple attic-mounted
VHF/UHF antenna with an amplifier, but still have dropouts when a
low-flying airplane passes.

I just found the URL listed on the plot for my local TV stations as:
