Hi Steve,

For transmit, there's nothing to "gain" by it.

Success generally floods the marketplace and few complain about not
finding resources to make a knock-off.

Yes, I know there's nothing to gain in terms of performance. However,
I have very little space to work with. I have a 1 meter diameter loop
installed in my (tiny) attic that works very respectably on 10-30
meters. It won't get me onto 40 meters, though, and getting onto 40 is
either going to require a much larger diameter single-turn loop, a two-
turn loop, or a much more robust capacitor. Trying out a two-turn loop
seems like it would be the easiest and least expensive alternative,
and I already have the copper tubing I would need.

Two 1m dia turns will cover 40 with the same variable capacitor, I think
that is all you wanted to know!!! Experiment ...
