Last time out, we broke the Create Rotator. We fished out the Yaesu G-450 and we're going to try again - this time with the whole 13m (42.5-ft) and a 6:1 pulley. Wish me luck!

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. ALl lines will be replaced with Dyneema after we've sorted it all out.

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 rotator will eventually be replaced. The vertical force specification on the G450 is 200Kg. I broke the Create RC5-1 which had double that. There are no sideways loads on the base of the tower so I only need to worry about vertical loads.

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

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

The "disaster" video is here:    • Tower Project - Disaster - When It Go...  

We covered the planning of this tower on a previous video:    • Cheap Tilt-Over 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 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), add an extra guy-point 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.
