I agree with the need to use an all channel antenna aimed south. I would slightly favor the HD7084P for it's added gain in the L-VHF band (real CH-5, WMC needs the gain).
If you have more than one TV to connect, a rotator may prove frustrating when the antenna needs to aim in more than one direction at the same time. There are other options...

If I was installing a second antenna for the WSW signals, I'd also consider the Winegard HD7698P.
Given the moderate to weak signal levels, the Antennas Direct PA-18 is high on my list, though the TVPRAMP1R is a good preamp as well.
