Consider a pair of 91XG antennas stacked horizontally 1.5 or 2.5 wavelengths apart. (about 3' or 4.9') The 91XG by itself will attenuate WCPO & WUPX by roughly 30 db. The stack would improve that to 50 db, which might be just enough.

What do you mean? Two 91XGs would bring his dB gain to 50dB? One 91XG is rated at 16.7dB.
