Fortunately, I now have the luxury of no antenna restrictions. This was
one of the reasons I moved in 1990. I do have a lot of experience with
attic and "hidden antennas" between 1983 and 89. I can emphatically AGREE
that the
loop will work better on the roof rather that in the attic. It will work
even better if you put it 6 or 18 inches above the shingles. with small
guage wire (We are talking qrp and low power, right?) it will be invisible.
I found similiar improvements with random length dipoles fed with ladder
line.
Other plus....less tvi, bci, etc
