Hello to all-
Does anyone have a rule of thumb for the expected lifespan of coax?
In my case, I am using Belden 8267 (rg-213/u) for my HF yagi.
After 4 years of service, the jacket is covered with a maze
of hairline cracks, although jacket integrity seems fine.
Worse yet, the cable is exhibiting nearly 2x its specified
attenuation. I live in Southeast Michigan, so the cable sees
temperatures ranging from -15deg F to +100deg F. I've checked
the connectors and they seem tight, so I don't think they are
causing the problem.
Thanks and 73,
