[Boatanchors] Coaxial cable question

[jeremy-ca]

That depends upon the initial quality of the cable and the enviroment it is 
in.

The only true test is to measure the attenuation.

Since RG-8 became a rather generic nomenclature once RG-213 became the mil 
spec, it could be anywhere in the loss column by now.

Foam dielectrics age better than the solid version. I have some 1980's 
Belden 8213 and 8214 that still meets published specs.
