This post is short and sweet.
If you click here–Electrically Small Resonant Loop Antenna for Mediumwave Reception (PDF)–you can download a copy of Bob Colegrove’s excellent paper on the Electrically Small Resonant Loop Antenna for Mediumwave Reception.
He has actually built this antenna; it works; and he uses it often. Perhaps you might want to build one for yourself. As an added bonus, Bob is an excellent writer (in my not-so-humble opinion). What’s not to like?

Nice work Jock.
If I had time and patience these days I would build one.
I have built 2 large loops based on the design of Shawn Axelrod. One wood, the other with PVC.
Any loop 3 feet across and larger always works very well.
