Default Wire diameter vs Impedance

Is the lack of an "end-effect" why a full-wave loop has
to be made longer than 2*468/f?

=======================================

Cec, I do wish you would stick to metric dimensions instead of feet
and inches. It would make life much easier.

You've read about it in a book. Have you ever measured it? Has
anybody else ever measured it?

Although a continuous loop has no ends it does have a small opposing
mutual impedace (both L and C) between one side of the loop and the
other. This affects the velocity factor. The mutual impedance does
not exist when the wire is all in one straight line.

What explanation do YOU have to offer?

Reg.
