don't tell AC0C antennas in an attic wont work....
#1 Antennas inside of an attic are often really poor performers
precisely because there is enough stuff up there to absorb a lot of the
RF, although not all of it is wood. I don't think shingles are all that
transparent to RF, for example, especially when wet. Attic antennas do
enable contacts, of course ... after all, even if only 5% of your 100
watts is escaping the attic you're no worse off than if you were running
QRP to a decent antenna. The problem is that most people using an attic
antenna don't have anything better to compare it against. if they did,
not many of them would be using the attic antenna. Besides, wood inside
an attic is almost always bone dry ... people used to make insulators
out of that stuff.
