Anyone Recognize this Coax?

[nbkhwjm]

Ive not seen coax quite like this, and im sitting on about 1000 ft of it.. Im planning on a rather simple (prbably ineffective) impedance test to see where its at, but wanted to see if it looked familiar to anyone..

there is NO WRITING on the jacket, and the spool is long gone...

its got a jacket, full braid shield, thick dielectric (not foam), another shield braid, thin dielectric then the center conductor..

its about the size of RG-6,
definitely larger than RG-58 or 59
but smaller than RG-8

Ideas?

What you have there is triax! Triaxial cable - Wikipedia
It is most likely 50 Ohm.

yea i just discovered there is such a thing, with 1000' feet of it, id like to put it to work... Ill hook it up tomorrow and see how it does... I was thinking of setting up a 50 ohm dummy load at the end of 10', send a sig in and see if the SWR is 1:1 (50ohm) or 1.5:1 (75ohm)..
