Hi Colin, I have a friend who used a copper loop antenna
approximately 36 inches in diameter to conduct DX with European
stations using I think 10 watts. He lived in an apartment and
was using a digital protocol but I can't remember which one it
was other than it wasn't PSK 31. Pretty amazing stuff, but each
contact takes a while, kind of like it will be when we have folks
living on Mars! 73, Jim WA6EKS

I have yet to hear one of these actually on the air.
The theory is logical, and the science supports it, but in real
world
performance I'm not sure how successful they've actually been so
far.
The key to using a tiny HF antenna is to communicate with people
who have
big high gain antennas hi hi.

Here is a very interesting article on small HF antennas and the
theory
behind them.
PVC pipe and fruit cans, both readily available.
