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?

Shouldn't you be addressing Art Unwin with that? ... it's he who's proposing
the idea, not me.

Perhaps the behaviour of Outlook Express has led to confusion (again?),
despite my leaving a double line space between the OP and my comment.
