This is a 12m tower project and the guys are dual-use as a 40m 4-Square switchable antenna array. So there will be 4 vertical antennas coming off each guy point. Accuracy is mandatory for both the 4-square (impedance matching and gain etc) and you'll see shortly in another video why they need to be spot on because when we move to a non-stretch Dyneema rope, all 4-guys need to have same tension when the tower is lowered and raised. Further, the tower needs to be totally detuned from 40m. More of that in later video. Temporary yagio going up on the top to give me time to develop the quad.

We covered this tower on a previous video:    • Cheap Tilt-Over Tower Ideas for Ham R...  

And the start of construction is here:    • Building the Antenna Mast Foundations  

We also made a video about Quads - which is the target of this tower..    • Cubical Quad Antennas, Towers, Delta ...  

And here is some information about 4-Square antennas which will surround the tower (tower will be de-tuned off 40m):    • How does a 4-Square Antenna Array Work?  

In this video, I drilled out the scaffold guys for the eye bolts, fitted the rotator, fitted the falling derrick system and the first scaffold tube to deliver the first piece of the tower.

The next video is when we fit the first tower section, fit the first lines, do a first placement of the vertical tubes and do a test-lift.

The video after that is when we fit the top of the tower, fit all the lines (ropes) and make the tower fully operational - as well as site the 4-vertical elements (non functional).

The next video after that one in this series is to make a temporary yagi mono-bander for 20m and fire at USA. Then finally, rotator cable, ethernet, control wires etc up the pole.

Finally, we lay the radials down for the 4-square and connect up the control box.
