Since non plenum rated cables no longer meet codes, there is an
opportunity to buy the NOS of it cheap on ebay. I've scored a couple of
ebay 1000' spools of tinned double braid "rg59" Belden, 20 ga center for
around 10 cents a foot. I think it's the precision video cable Jim
mentions.
Here is some Belden single braid at 10 cents per foot, free delivery!!
It is worth a deep search of ebay "belden rg59" now and then.

Or RG6 might be cheaper but there are at least a dozen varieties that
Belden makes, so keep the catalog handy. With Belden NOS so cheap why
take the risk of Chinese junk?

I've seen some data CCS center coax. It matters below about 5 MHz.
What is your application for this coax? There's a Belden product with
a double copper braid shield and a solid copper center. Look up 9290.
About six years ago, I bought a partial spool of a very comparable
product at HSC with Pasternak's name on it. I still have some of it.
At the same time, I also scored a nearly full 1,000 ft spool of 8213,
which feeds my high dipoles.
These are classed as analog video cables, where copper loss at low
frequencies was a big deal. Since the transition to digital video, I
suspect they sell a lot less of it. :) There are a lot more -- see
pages 6.38 - 6.39 in this link.

Most RG-6 has a copper clad steel center conductor.
Does anyone have data on what the loss of this
type of cable is at 1.8 MHz compared to solid
copper center conductor? Any suggestions
for RG-6 with a solid copper center conductor?
I see Belden 1694A, 7915A, 7916A and 9248 in
the catalog, but don't know if any of this is
available in distribution. Can anyone suggest
some good distributors to buy quality RG-6?
Thanks.
