[TowerTalk] Tower Build

[Mike Reublin NF4L]

Take a look here http://www.nn4zz.com/tiltplate.htm or Google for antenna hinge. I built one, works great.

It has 9 elements on a 30 foot 5-section boom. At first, after tilting the tower over, I accessed the yagi with the use of a 12' step ladder. Access to the 10m λ/2 vertical on top of the mast above the yagi was impossible.

Removing two sections of boom + elements allows me to tilt the tower to COMPLETELY horizontal. I now do all antenna work with both feet on the ground. No crane needed. To keep the yagi from pinwheeling, I use a simple clamp assembly to hold the mast when the yagi is partially disassembled.

The main thing I got from the book was to try to do it according to zoning and permitting requirements. I did. His collaboration with Ward Silver NØAX on "HF Tribander Performance - Test Methods & Results" was a good read as well. When the C-4XL came available, I jumped on it.
