A rotator will be a source of frustration if the antenna needs to be aimed in two different directions at once.

So a 4-bay panel such as a DB-4 or CM4221 aimed at 247° (compass) will get WIVT and WSKG. If you pan toward 208° you might be able to get WQPX without loosing the first two. (It's worth trying)

Then aim a Y10713 between 247° and 210° to give you the stations on the high VHF band (WBNG, WICZ, WBRE and the redundant CBS affiliate WYOU).

Use a CM7777 preamplifier to combine the signals into one coax.

You are in an area shadowed by terrain. The signal estimating formula is indicating a not so unusual phenomena, as you go up, at least initially, the signal strength gets worse not better. You can put a variety of elevations into the TVF software to see what altitude you need to reach in order to expect better signal strength. If you find a practical elevation, great, mount up high, otherwise simply mount in an unobstructed, convenient location (Be prepared to 'walk the roof' though, in your situation you may find 'hot' and 'cold' spots within a few feet of one another). When you mount two antennas on one mast, it's best to maintain at least 4' of separation. More is better.
