Thanks Jim/K2TL 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! |
