Thanks for the advice. Relocating this antenna will be tough...it's large and currently attached to a mast off my chimney.
I think I'm going to try re-aiming the antenna to a point just south of Chicago. I think I might be off to the north (to avoid my neighbor's house - and aluminum siding) so aiming to the south of his roof peak might get to a better aim at Chicago than my current direction.
Any suggestions for a more directional antenna?
The one I'm using now is similar to this:
