I would say your problem is CBS and somewhat PBS. The other majors are all on UHF and a fringe array pointed just a smidge eastof true north should get them. CBS is on VHF high and is weak. I am guessing it will take a long mast VHF-H antenna in addition to the UHF array. Will definitely need an amp. These stations are all 2-edge, which is always a crap shoot. Try running the tvfool report again with an antenna height of 40'. I bet you see big improvement. If so, I would really recommend putting it on your roof or adding a tower.
