This is the full video, assembled by Chris Hockaday, from a bunch of my poor cell phone videos. He's helping me outfit the workshop to produce much better videos from my projects.
I've built many of these over the years, and they're much stronger than they look. Here's the video...
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...
I have some bits of old coax that I wanted to test. I have some coax in use that is easily 50 years old. I sweep and check for loss at various frequencies, check for moisture ingression, and put them back in service if OK.
