Tower Project - Disaster - When It Goes Wrong

It went wrong. Can we fix it?

This is a 12m tower project for an HF Yagi / Quad etc. long story.. BUT the guys are dualuse as both a 40m 4Square switchable antenna array as well as the tower.

So there will be 4 vertical antennas coming off each guy point. Accuracy is mandatory for both the 4square (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 nonstretch Dyneema rope, all 4guys need to have same tension when the tower is lowered and raised.

Further, the tower needs to be totally detuned from 40m so we have a fibreglass insulator to change the resonance to around 9MHz. We COULD add a further insulator above the rotator to move that to about 24MHz. More of that in later video. There will be a temporary yagi going up on the top of this tower which will give me time to develop the multiband quad antenna.

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

"Part 1" is this one    • 40 ft / 12m Tower Project  Guys and ...  

We covered the planning of this tower on a previous video:    • Cheap TiltOver Tower Ideas for Ham R...  

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 4Square antennas which will surround the tower (tower will be detuned off 40m):    • How does a 4Square Antenna Array Work?  

The NEXT video in this series 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 4vertical elements (non functional currently until we connect it).

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

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