The stations from Baltimore should do well with a good outdoor antenna. The only questionable one I see is
WUTB-24. MPT is on an adjacent channel &
very strong.
The proximity to BWI shouldn't be an issue with a good
directional antenna like the Winegard 7694. An omni antenna would likely suffer from dropouts with signals bouncing off nearby aircraft.
I'm 40 miles out from Baltimore & only see an occasional glitch on 11 & 13. (UHF is unaffected) Planes from National Airport fly right in front of where the antenna is pointed.(About 2 miles out)
