[TowerTalk] Coaxial Cable Question

[Pete Smith N4ZR]

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.

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.
