Good points.

I wonder, too, if such a super-tall antenna works as well on digital UHF 
as it did on analog VHF? Granted there's not much population directly 
under the antenna, but still the usual UHF low-TPO/high-gain-antenna 
seems to me as though it might still shoot a fair amount of signal over 
the heads of the target audience.

Did the KVLY folks have any comments about their DTV coverage vs. analog?
