John and others - I recently bought 10 feet of what is sold as surplus RG-400.  At least it has silver-plated shield and center conductors, though no printed markings.  My plan was to wind a common mode choke for my 160-meter Inverted L. I was using a #31 big snap-on, and found it impossible, because of the stiffness of the coax, to get more than about 8 turns on the core, and they wouldn't lie down at all.  The jumper I have is extremely flexible, and would be a cinch for the job.

Why do you want this?  RG-400 is available surplus for $<2 ft, Amphenol connectors fit it perfectly and it is excellent for connecting equipment in the shack.  I have used Teflon coax outdoors too with no issues.  If you hate soldering you can buy RG-400 / Amphenol 83-1SP assemblies at DX Engineering.

Maybe 8-10 years ago at Dayton I bought a 3-foot jumper of coaxial cable
with PL-259s (and reducers) on both ends.  It looks like RG-400, about
the same diameter and with the clear jacket, but is much more flexible,
and the braid is not silver-plated.  Anyone know what this is, and where
I can get more of it?
