World's oldest coax cable

World's oldest coax cable

Ok, so it's probably not really the oldest. But it's the oldest piece
of coax I've ever seen. Have a look at:

This is a piece of RG-8 coax I found in a box, and the date stamped
into the coax jacket is July 1944. That got me to wondering - when was
coaxial cable first made available for sale? Wonder what a foot of
RG-8 cost back in 1944?

Coaxial cable was used in the early 30s for television transmission. I
have a unit made by RCA in 1931 with a one inch diameter coaxial cable
on it.

My Father (W3CRS) had hardline he used in the 30's.
It was a VERY interesting design.
Ceramic buttons crimped in place on the copper pipe center conductor.
The Center conductor (and buttons) all pulled out of the copper outside
pipe as one peice!

I was maintaining wireless Set #19 installations in England in 1942 using
co-ax cable and the earlier MK 1 was being used in the desert in North
Africa before that, also using co-ax connectors.                       &s

You might be right---there weren't too many coaxial connectors on WW II
military radios until late in the war..  The earliest mention I could
find was in a timeline:

1936 - - First coaxial cable installed between New York and Philadelphia
made available for multi-channel
telephone tests. The coaxial cable was demonstrated on November 30th
when Frank B. Jewett, president of Bell
Telephone Laboratories talked with officials of the FCC in Washington.
