Mike,
From an electrical point yes, but mechanical strength is poor especilly in
warm weather.

The white stuff can tend to get brittle out in the sun. Painting it will help with this somewhat. My 70cm antenna was modeled after the cheap yagi design and had a white PVC boom that had been painted gray. When lowering the mast to do some rotator maintenance the antenna brushed a nearby dogwood tree that the XYL refuses to let me cut down. The boom snapped right at one of the elements. This could have been brittleness or just the fact of where it struck. I can't comment on the tan (CPVC) pipe as I haven't used it. My replacement antenna will be using schedule 80 which is gray in color and much more rigid for the boom. 73, Michael, W4HIJ _______________________________________________ Sent via AMSAT-BB@amsat.org.
