Byron, I recall that K1VR, who used to operate a cable company, used the
rule of thumb of cutting off one foot per year stored outsdde from each
end of each roll. It's hard to imagine that this cable would be bad,
but if you know the length you can certainly put a connector on one end
and measure the loss.

Hello-
I thought I would ask just to be sure. I brought home some NOS Belden
RG-9A/U coax, still on a 1000' reel. The reel was stored inside in a radio shop
in Okla City, and the wooden spool showed no signs of exposure. I really like
to use the double shielded cables when I can. However, this cable dielectric
has a very distinct yellowed appearance. The copper shields are nice and bright
and show no discoloration, and the (gray colored) jacket looks nice.
Is this cable no good? I am thinking of installing connectors on it and
measuring the loss, as I have no instruments other than an MFJ-259B ant
analyzer.
Any comments on this subject appreciated, as I have saw a yellowing in the
dielectric of other cables.
Thanks, Byron WA5THJ
