[TowerTalk] What coax is this?

[N4ZR]

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?
