Thus, if you literally make the ladder line into a true ladder by
fixing a lot of conductive cross rungs on the ladder, the applied
current will cross over at the point that the circuit is resonant.


Hi Chris,

So, you want to turn a massively shorted thin transmission line into a
radiator?

How does the current get past the first short? It cannot, so that
string of shorts up the line are redundant and you can remove them.
This leaves you with a very small loop very close to the transmitter.
Almost every ham has tried working into a short and has never found it
productive. Have you tried it?
