Significantly less impulse noise and interference. Also the allocation
formulas favored coverage (higher permitted EIRP) in the low UHF
channels and penalized coverage (actual signal levels failed to meet
expectations) in VHF. Except for some special circumstances the
"golden" channels are roughly 19 through 40.
