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.
That is not schedule 40 and I did not use the light irrigation
pipe. I have been in Arizona (for 29 years) and can not say I
ever used PVC for anything. I used Galvanized pipe for sprinklers
too. But that was about thirty years ago and before.
I However we had a pool heater from the black flex pipe which
lasted for many years. It is no good for RF though!
