Most digital channels are currently in the UHF band, and I have had wonderful experiences with my two UHF antennas: Washington DC (55+ miles), Baltimore (90+ miles) during evening hours, Richmond VA (51+ miles) and Charlottesville VA (53+ miles). I use used two Channel Master 4228 antennas with matching CM-7775 pre-amps.
I have been using these antennas for the past fours years, however with the Analog Shutdown occuring in February 2009 some broadcaster will be returning to their former VHF frequency. I'm not sure how this will affect local broadcasters in your area, but it is certainily someone to consider as we are nearing 2007. In my case, three of the broacasters in the DMAs I mentioned above will be moving their DTV antennas over to VHF, which will complicate my OTA reception.
