Hello, Svyn:

If you aim a VHF/UHF combo antenna south at about 187 degrees magnetic, you have a good chance of getting WPGH Fox down to WTAE ABC, if there are no trees or other buildings in the way.

A Winegard HD7694P would be suitable outside. If it is in the attic, the signal strength is difficult to predict because of differences in construction. Try different locations in the attic with a temporary setup and one TV before drilling any holes. If the TV has a signal strength indicator that would help.

If the signals are too weak in the attic you can add a preamp like the Channel Master 7778.

If that doesn't work, the antenna will have to go outside.

If outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.
