I live in East Bradford Township, Chester County. With an attic antenna, if I tune to channel 67, I am more likely to receive the signal from the PBS station in Hagerstown, Md. than the signal from WCAU-DT. I am also receiving the signal from WBAL, 11-1 (59), NBC from Baltimore, once per week, which is one time more than I receive the signal from WCAU-DT.
I moved from East Bradford to Malvern a year ago. In East Bradford (Skelp Level Rd, up on the hill near the East Caln border) I was also using an attic antenna. I had no real problems receiving WCAU if it was aimed properly and I used a good UHF amp (not radioshack - Channelmaster 7777 I think). Also I replaced the old RG59 cable with a new quad-shield RG-6 cable, which helped as well).
Sounds like your attic antenna is non-directional. Switch to a directional antenna (as directional as possible) and it should help a lot. It will mean losing the MD stations unless you put a rotator up there. If you only use it for digital, you could go with a UHF-only small 4-bay vertical array like the 3023(?) from channelmaster. Not too expensive either, and far smaller than directional UHF/VHF antennas (or even UHF yagi's).
In Malvern, with a directional and the preamp, and with a direct line of sight to the towers, I get them all well, and often get WWAC from Atlantic City (!) cleanly. Must be at least 80 miles, maybe 100. (I am on top of a ridge at Valley Forge).
