Glad to be of service :)

Rubbish. Many posts gave the 1.7*Sqrt(i/p pwr) = arc length, so I did not
repeat it.

I think you will find that many answers gave a rule of thumb. Try reaeding
the posts again.

Again the 1.7*Sqrt(i/p pwr) was given many times, however this gives the
minimum height, you were asking about the *maximum* height. Many people also
tried to piont out that this was not a reasonable question and show you what
you should be asking.

I'm glad you now appear to understand, (from reading your other posts) and
hope your coil turns out well.

Tom.
