As you know, I built that slotted line that works fairly well for load

antenna work.
A pick-up loop will do the same thing for ladder-line.

I've always ignored the use of twin lead for impedance measurement. But,
it makes sense. I may try building something like that, just for fun.
I certainly havent thought this "twin lead" line thru but it seems that
one could be easily built from a length of PVC pipe with wires attached to
its sides.
This seems too easy and relatively accurate for "home in the garage" use.
I'd bet I can find some info on the Internet for FM and TV frequency use.
Thanks for jogging my mind.
