So you want to get the majors from Erie? The majors 24, 12, 50, 22, 16 you should be able to pick up with an AntennaCraft HBU55 or HBU44

The majors aren't terribly weak, so you should be able to do without an amplifier. I'd try it with a direct wire to one TV and then if you need more amplitude to compensate for added splitters, you can add a mast mounted preamp or a distribution amplifier.
