Well, I picked up 4 4 1/2 ft antenna mounting poles along with 2 u-bolts yesterday. I had a 15 inch piece of 3/8" all thread. I bored a hole at the top of one of the poles and put the all thread in to create a perch. I painted the pieces (except the all thread for a contrast). I hope to get it out today or tomorrow. I hope he doesn't find the all thread too sharp/rough.
