Ok, I'm not sure if I've asked this or not already so forgive me if I have. I finished building my DBGH a couple of months ago and it works great. It's made from grey 1/2" PVC electrical conduit with regular PVC tees and elbows for the framework. I used 1x2 inch fencing for the split screen and #4 gauge copper wire for the element with #10 gauge copper for the phase lines. All the PVC is painted dark green. I ordered chimney mounting hardware and I'm getting ready to mount it, but I have a couple of concerns. 1. What is the life expectancy of something like this? The mounting spot is not easily accessible and I don't want to have to replace anytime soon (3 stories up). 2. Anyone know how well one of these will hold up to wind?
