Tower Sidearm, pt1

 This is a simple and sturdy antenna mount / tower sidearm for Rohn 20 & 25. I've been building these for around 40 years, and have some that are 30 years old and still in operation. This first part is the part that clamps to the tower leg. Using a 1" PVC "T", cut the back side off so the round part that goes around the leg captures a little more  than 1/2 the tower leg diameter, like maybe 190°. It's not critical, watch the video below...
