efficiency. :-)

It was done in 1936.

But I still think I prefer coax...
Their "ladder line" looked to be a twisted wire feeder.
The call on that vehicle was W9MSY...

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.
