To clarify this a bit, the government recently auctioned off the 600 Mhz TV band leaving only channels 14 thru 34 in the UHF band. Nothing changed with the VHF band. Back in the old days of analog you could not have adjacent channels in the same market. For instance, you could not have channels 2 and 3. But wait, you say there are channels 4 and 5 or 6 and 7 in your city. Turns out there is a frequency gap between these channels. This basically cuts the number of channels available in half. Now with the advent of digital, adjacent channels are allowed, so the impact of the frequency auctions are not as drastic as appears. Most of these channel reassignments are within the UHF band, so most of the TV broadcasts will remain UHF. Before the repack about 25% of TV stations were broadcasting on the VHF band. I don't know what the percentage will be after the final repack.
