24-Hour Stress Testing 2-Stations, the new Yagi and the new Band-Pass filters. 20m is currently on this antenna: yagi:
Last time out, we had a successful first lift and have had it guyed and upright for a week before fitting the control cables for the rotator.
Before that, we broke the Create Rotator. We fished out the Yaesu G-450 and did a successful "launch" with a 6:1 pulley.
This is a 12m tower project for an HF Yagi / Quad etc. long story.. *BUT* the guy points 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 G-450 rotator will eventually *have* 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: https://youtu.be/SbMy_82XRDM
"Part 1" is this one https://www.youtube.com/watch?v=O_pQN0pMvmA
The "disaster" video is here: https://youtu.be/4eiEd00N5GU
We covered the planning of this tower on a previous video: https://www.youtube.com/watch?v=AmgUGuoudb4
We also made a video about Quads – which is the target of this tower: https://www.youtube.com/watch?v=3r9ff32j9Yo
And here is some information about 4-Square antennas which will surround the tower (tower will be de-tuned off 40m): https://youtu.be/joWUH2PgGZg
Next video in this series is the full-blown QRO test.
Finally, we will lay the radials down for the 4-square and connect up the control box.
Enjoy. And Subscribe you b*ggers! Or even just give me a nice comment!!

Kristen McIntyre K6WX, First Vice President of the ARRL presented at the Tassie Ham-E-Con Ham Radio Conference about "Ground is a Myth" and the intriguing cases of grounding!
@ARRLHQ
Ground is easy to understand when it means something you stand on, but in the electrical world, it’s a bit more complex—especially for hams. We pound rods into the earth, but why? Let’s dig into whether this all makes sense and what theory really says about "ground." Does it exist in any practical way?
