I had invited readers to the helical antenna pages of Kraus to support
my wave advance comparison to the progress of a threaded bolt. I had
looked at page 229 in the 3rd edition with its Figs. 8-8 and 8-9 or at
similar figures in an earlier edition.

Upon looking agin, I still believe the figs. support my bolt comparison.
In any case, I`d study long and hard before sarguing with Kraus.

I didn't quite grasp the purpose of your bolt comparison, Richard.
The only limits Kraus puts on helices is that they are helical -
anything between a flat single turn loop at one limit and a straight
line at the other.
