Your difficulties with WPXI stem from their use of ch. 6. Very few broadcasters stayed or returned to the lo-VHF (2-6) band when analog broadcasting ceased in 2009. The noise in that band, especially from electronics, is worse than what was accounted for when the FCC allocated DTV stations. Even TVFool's estimate of reception in this band is a bit overstated, so the noise margin is not quite what is predicted. Add the craptacular preamp that is probably overloading from local TV and/or FM, and you don't have much hope with reception.
Your antenna looks like it has elements to handle ch. 6, so try a high-input preamp like the Winegard HDP-269 first.
