Tuning curtains can be excessively iterative, unless one is satisfied with
the initial SWAG -- er, um, calculations. IME, the bends make it difficult
to get the lengths of the sections such that all the current loops and nodes
occur at the proper places in the wires of the arrays. I use a simple
double-loop-and-diode current probe, on a pole, to look at currents.
The currents toward the outer end(s) of the array fall off, as well,
reducing effectiveness with increasing size.
All that said, do it at least once, anyway, for the experience ;o)))
