This issue has a good antenna article on loop antennas but for some
strange reason the author seems to think it is only a good AMBCB
antenna. This antenna type is excellent for SW also. Depending on what
frequencies you want to the antenna to operate on and the circumference
of the loop you will not need a matching transformer. Closed loop
antennas are generally superior in urban environments with local noise
sources for a number of reasons.

There is also a good article on propagation by Tomas Hood.

Have you heard anything about those hula-hoop sized loops? If I can find a suitable tuning capacitor I might try building one. The directional abilities look useful.

Build you one Mike. You can't go wrong. Loops IMO are freeking killer-
I only have loops for the BCB. For some some reason I just can't
picture (even though I know it works) using a loop for shortwave. I
have three of them and use two of them all the time- without them
there is NO WAY I could have logged and received the verification
reports I have. What type of capacitor are you looking for? I have one
I am not using.....it's a good one- I forget the specs but I could
find out.
