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 dual-use as both a 40m 4-Square 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 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 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 multi-band 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 Rotat...   We covered the planning of this tower on a previous video:    • Cheap Tilt-Over Tower Ideas for Ham Radio ...   We also made a video about Quads - which is the target of this tower:    • Cubical Quad Antennas, Towers, Delta Loops...   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?   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 4-vertical elements (non functional currently until we connect it). 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 will lay the radials down for the 4-square and connect up the control box.
