However, I don't think I've ever seen a mobile tube rig feeding
ladder line - no doubt one day I will. We will probably talk about
efficiency. :-)

It was done in 1936.

Cover pix from a 1936 QST...Forgot
what month...
But I still think I prefer coax...
Their "ladder line" looked to be a twisted wire feeder.
The call on that vehicle was W9MSY...
With the short feedline run on a mobile,
even coax is pretty low loss...
I never used an SWR meter when I was a
novice...I had an old viking valiant that would
tune nearly anything...You didn't need a meter...
You just loaded it up to full plate current and went
with it...My TS 830 is like that to a lesser extent..
If it loads within the loading range, it's good nuff...
No point in even putting a meter on it...Adding a
tuner, would just add some loss...MK

Hi Mark,

Hmmm, the picture's kinda small, and the line looks like coax - or
maybe close ladder line. I will take your word for it as it makes my
track record for accuracy complete. :-)

Well, almost complete. Is the guy holding his pinkie to the radiator
measuring efficiency?

As a sidebar, the police were working 160M mobile back then too.
Seems coax was hardly an off-the-shelf item. Think they used ladder
line too? More probably direct feed.
