Greetings
Does anyone know if typical schedule 40 PVC pipe is UV
resistant? I
have some antenna projects in mind that will be built from
this stuff.
I suppose I can paint it for some extra protection, but I was
wondering
if it is necessary?

Thanks

No, PVC is not UV Resistant...

I have an antenna in a PVC case which has been on my roof (in the
SUN) for over ten years. When Can I expect the PVC to fail?

As soon as you bring it down to AZ. I have a 120' run of 2" grey PVC
from the house to the tower. It's mostly above ground with a stake
and clamp every 10'. It looks like a snake, the top side turns color
and it's cracked in a couple of places.
