You might not want to give up altogether on analog TV transmitters
either. I still don't know where the transmitters are, but during
recent slightly enhanced propagation, I was getting usable returns on
at least one sub-channel of ATV channel 2, 3, 4 and 5. And this is
on a 50MHz 6M halo, not any sort of directional antenna. In the
metro Detroit area, I could easily be hearing stations in
Canada. Have you tried monitoring each of the three sub-channels on
each of the 2-6 ATV channels.... with a decent antenna..... for
several hours to be SURE you can't hear anything?
