Via the Braund identification, I found a picture of your antenna. Looks like a dipole, but I can't tell how long it is. I'll assume it will provide 3 dB gain no matter what - a very generous assumption.
The goal for reliable reception is a noise margin of +10. The antenna will add to noise margin, so we're down to signals of +7 that should be reliable. The amplifier is bad news: the amplification has no effect on noise margin and the amp's internal noise (about 3 dB) actually SUBTRACTS from noise margin. We're back to needing a signal of +10.
Two stations, an LPTV and a repeater, WIBU-LP and W48DB, meet that criteria. Three more stations, two CBS affiliates and an NBC station have positive NMs, so they should lock periodically.
All this math assumes your antenna is in the clear. All bets are off in the trees. You cannot do better with the antenna you have.
Teleview, you want to take it from here?
