> What method would I use to determine/measure the self
resonance of my tower?
About the only way to measure it is with a big coupling coil
Bob, or sawing it in half.
Pretty much anything else you do adds reactance that shifts
the apparent frequency by quite a bit.
Modeling it is much easier, because you can insert a source
and look at the source impedance.
Why do you ask??
