[TowerTalk] Cable question

Looking for some assistance identifying some cable. The only writing on the jacket
is 1996 COMMSCOPE.
It's about 7/8 diameter, copper center conducter, a fairly stiff foam (I think)
dialectric and a full aluminum shielding (not braid).
I called Commscope and at first the tech thought it would be 50-ohm cable but all
their 50-ohm stuff with the above characteristics has more writting on the jacket.
So he thinks its probably more likely to be CATV cable at 75-Ohms. Probably has a
loss of about 1.8-2 dB per 100ft at 2000 MHz. That's gotta be pretty low for HF/6M!
Anyone out there familiar with this cable? I have a run of about 150-ft from my
shack to my tower and wondering if it is worth it to replace the buryflex I have in
there now with this stuff. I have 2 runs from shack to tower.
I'll probably get the cable pretty cheap...maybe about $25 for a couple large
spools but each only has maybe 150-200 ft on it. New N connectors will cost me
about $40 each. Then adapters from N to UHF.
The cable is pretty old....1996 but has been unused and on its original wooden
spool and stored outside.
