Those with an interest in building a Wellbrook ALA 100 setup for use on an
antenna rotator may want to check out my most recent blog entry (July 22nd).
I have pictures and construction details that describe the way I approached
the project.
I believe the ALA 100 is the most flexible and useful Wellbrook model for
the do-it-yourselfer. You can construct the loop in whatever manner suits
your abilities and requirements.
My use of the ALA 100 is primarily for DXing foreign medium wave signals,
with a secondary use of hearing third-world broadcasters on the tropical
bands. I've heard of some amateur radio operators using Wellbrook antennas
for a receive-only solution, too.
