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?

These are my opinions.  I hate spam.
