[Boatanchors] RE: [Antennas] Coaxial cable question

[Alex]

...darling, I'm still using cables from the Six Day War (1967) and they're
still good!
As long as they don't develop cracks in the insulation and don't become
corroded they have practically infinite life.
If you can measure the loss of the highest frequency one and find it
reasonable, don't touch anything.
Remember the old adage: if it works, don't touch it!
Anyway, the new ones will probably degrade faster than the old ones.

Subject: [Antennas] Coaxial cable question

Hello;
     I have been using RG-8 and similar coaxial cables for my ham antennas
from 7Mz to 430MHz. Some cables are over 20 years old and still seem to 
work well. I am thinking of replacing some worrying that they may exhibit
high loss
due to their age. Does some has information on cable loss versus age?
If they do age then what is useful life time of cables?
