I'm familiar with that usage, but I don't know why it's interesting in the
context of coax.
I think the key idea is that the insulation is thin so you can get lots of
turns/inch in a transformer.
I don't understand what a "helix" is in coax, or rather I don't appreciate
the numbers. I'd guess that the "center conductor" is constructed as a helix
and that increases the inductance/meter by a whole lot, or something like
that. But isn't there a sqrt in there?
