Given the predicted signal strength and path profile of WGPX, I would be less than 100% certain of a single fixed aim antenna solution. But I would try the 4-bay panel as JC has suggested.

I ran an FM Fool report based on the ZIP code and see that WPTI-94.5 is strong enough to consider as a potential source of harmonic interference. 94.5 MHz * 5 = 472.5 MHz (UHF CH-14 is 470 - 476 MHz).

Worst case you may need a rotator or a dedicated fixed aim antenna like the XG-43 or 91 or 9095 with an FM trap... If I proved that a fixed aim antenna was needed and I needed to split the signal to several sets, I would opt for a high gain antenna rather than use an amp (which would be the likely point for FM IMD to be produced). But again, try the suggested 4-bay panel antenna, there is good reason to expect success. The 4-bay aimed directly at WGPX should be able to drive a couple of sets or more. If you can't find an aim point that works for all the stations of interest, the 4-bay will provide enough information to guide your selection of the solution (rotator or second antenna).
