[TowerTalk] What coax is this?

[N4ZR]

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.
