Recently, a co-worker quizzed me on, "What would happen if you were to apply reverse polarity to the Energizer Bunny?". Having no idea, I asked, "What would happen?". The answer is he'd keep coming and coming and coming...

   Thanks ThaDood for the very valuable material for repetition and your own experiments.
It gives you to think, instead of placing a typical magnetic loop in the garden, you can see a better SULA directional antenna. The other two parts of the publication are now available.
 When I am old enough that I no longer climb a tree, this antenna will be my salvation. ;D

Sounds promising. I've been pondering several inexpensive readymade and homebrew amplified loops.

i think LNA instead of balun should work much better. Or aplifier like Chavdar Levkov amp.
