A deep-fringe all-channel antenna should do the trick for you. Look at the Channel Master Crossfire 3671, or the Winegard HD-8200 or the Wade-Delhi VU-936SR with the optional VU8PZ powerzoom UHF attachment. For a preamplifier, try a Channel Master Titan 7777 or a Winegard AP8275. It doesn't look like you'll need a rotator, though...
