Is this still manufactured?  Belden discontinued it several decades ago. 
I found a 250 ft spool NOS at the Milwaukee hamfest in the '70s and 
added to my stash, figuring I would sometime find a use for it. I did, 
nearly 30 years later, to feed a dipole that I also wanted to load as a 
Tee vertical. I still have that line. I also have a few short lengths of 
heavily used Amphenol that's similar to it.

The Belden cable has fairly low loss at low frequencies, but rises 
quickly above 10 MHz.
