That's easy to test, but it would break the continuity of the shorted turn
which is the current probe.  I think I have some 1/2" dead soft copper in a
3' coil.  If I have a chance. I'll look into that.

I think the toroid is essential.  It becomes the core of the transformer.
The copper tube is the primary and the output link to the coax is the
secondary.  Without the magnetic properties of the core, no signal is
transferred.
