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 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? At some future next time when a gusty wind applies enough vibration to cause the brittle case to stress fracture and crumble. Note* - Gusty winds are often accompanied by precipitation which will give your newly exposed antenna a good soaking. -- JK Can't tell what you are trying to say. I live in California in an area where we get 70 to 90 MPH winds several times a year, sometimes the (water proof) PVC gets rained on, but not much (11 to 36 inches a year. Sun for about 325 Days a year. Still see no damage of any sort. I do not however expect it to last forever, but then neither will I! BTW: the antenna is Aluminum wire and the water would not damage it either, but then I can't hang the wire out in the wind! It is just several strands of #15 electric fence wire. (Four per element.) |
