There is no foil on the roof.

I live in a condo, so I'm fortunate that I actually have access to the attic. Putting something on a pole on the roof is out of the question.

The only barrier I can possibly see in the attic (other than the roof and asphalt shingles) is the brick of the exterior wall. I don't believe that would be in my line of sight, though.

I can try sticking a small set-top antenna up there, but I have little hope.
