Looks like you have Pittsburgh to the SE and Youngstown to the NW. What height did you use for the antenna? Rerun the prediction for the right height to see if some of the weaker stations (like WTAE) come up in signal. BTW, too bad you don't see WTAE's fill-in translator on ch. 22 better.
You have VHF and UHF, so you need an antenna such as the AntennaCraft HBU-22 or HBU-23. Aimed to the SE, you'll get all the Pgh. stations. It is possible to get both markets with a 4-bay bowtie antenna with NO screen. I don't know of commercially-available antennas of this design, but you can order an
easily assembled kit
here (get the 9.5" size). Aim SE/NW and you'll get a ton of stations. You might also benefit from a pre-amp (Winegard or ChannelMaster are good brands).
