Just be sure to test in your attic with some simple-but-known-working setup
before you spend a lot of effort/money.  For reasons that I don't
understand at all, I could not pick up ARISSat-1 from the attic, but it
came booming in on my HT standing outside.  I have just regular asphalt
shingles as far as I know, and wooden beams.  But SOMETHING was blocking 2M!
