When I found it, quite by accident as Susan mentioned it one day as I was 
lamenting the lack of such a cable, as flexible and well shielded as her 
type 7559 video cable was,  a cable that I have used to replace the about 5 
miles of the West Penn stuff that had been built in 3 months before I 
walked in the door in 84 to be the CE, and found I couldn't keep the color 
subcarrier out of the rest of the system due to the very poor shielding of 
the West Penn stuff, so the first runs replaced were the color subcarrier 
runs.  Which I found once I had started to replace them, I had to replace 
the rest as quickly as I could in order to get things back in phase, the 
7559 with its foam core was also about 8% faster than the West Penn, with 
correspondingly lower higher frequency losses.  In the end I had to redo 
the DA's too, replacing straight ones with delay adjustable ones before I 
finally got it all back on the same phase.  With the adjustable DA's, then 
I could treat the rest of the cable replacement in groups the individual DA 
fed.  In the analog days, keeping every input to a 24 wide video switcher 
in color phase was damned near impossible, so I finally set myself an 
allowable error of 5 degrees, which corresponded to about 4.5 feet of 7559.  
Best for my sanity (what little I had the first 3 or 4 years while I was 
trying to make a tv station out of the crap I agreed to maintain) that way.

Funny part about tracking the color was that I got half my off color 
reports from a color blind operator, who because he needed to, quickly got 
as adept at reading the vectorscope as I had been for 25 years already.  He 
is still there, Director of IT Operations now.

I'm probably boring the list by now, so I'll get me coat. :)  Thanks for 
reading.

Cheers, Gene
