Hi, 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! 73, Burns W2BFJ _______________________________________________ Sent via AMSAT-BB@amsat.org.
