After weeks of planning and fabrication, I finally fitted a 12 V winch to my ham radio antenna mast — and it works beautifully.

This video shows the full process of building a self-lowering tower using a falling-derrick system. From drilling and painting the custom angle-iron bracket to wiring the remote-controlled Winchmax unit, every stage leads up to that magical moment when the 14 m mast lowers itself effortlessly.

🔹 Tower height: 14 metres
🔹 Winch: Winchmax 12 V (1200 kg)
🔹 System: Falling Derrick with shock-absorbing mooring rope

The end result? A tower that can be safely raised and lowered at the touch of a button — no sweat, no strain, just solid engineering.

Stick around for the drone footage — it’s one of the most satisfying builds I’ve ever filmed.
