[TowerTalk] Coaxial Cable Question

  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
