I would think VHF, especially low-band, would have far better coverage than any UHF. Why would they stay UHF?
IIRC, Low-VHF stations are very susceptible to interference, so most are abandoning their VHF assignments. I can give you specifics for AZ stations.
Of all the low-VHF stations in AZ, only KNAZ 2 Flagstaff is going back to its VHF assignment. KFTU 3 Douglas (36), KTVK 3 Phoenix (24), KVOA 4 Tucson (23), KPHO 5 Phoenix (17), KMOH 6 Kingman (19) and KUAT 6 Tucson (30) are all staying with their UHF assignments.
Most of the high-VHFs are going back to their VHF assignments. Exceptions: KVYE 7 El Centro CA/Yuma (22), KCFG 9 Flagstaff (32), KMSB 11 Tucson (25), KOLD 13 Tucson (32) and KSWT 13 Yuma (16).
The only other station I know in the region that will be low-VHF is KVBC 3 Las Vegas. That lucky station got channel 2 for their DTV assignment while all the other Vs in the city got high-VHF assignments.
