When my 60 ft (18 m) antenna mast came down in a storm, I had a theory… Actually - everyone had a theory.
- Too many guys.
- Not enough guys.
- Angles too steep.
- Rope stretch.
Turns out… we were all wrong. In this video I rebuild the tower and explain what really happened — including the exact failure that brought the whole system down.
We also look at:
- Guy angles and geometry
- Wind loading and bending moment
- Why rope stiffness matters more than strength
- Why the top section behaves differently
- And how the rebuild improves the system
The original trigger was simple. The way it failed… wasn’t.
👉 One missing shackle pin started it.
👉 Rope stretch finished it.
We’ve now rebuilt the tower, upgraded the guys, and the next step will be switching to Dyneema.
If you enjoy practical antenna building, real-world engineering, and learning from mistakes — you’re in the right place.
