I removed my old home brew Stack Switch from tower 6 and mounted it at the bottom of tower 4 to switch all my 40m antennas.
In tower 6 I mounted a new Stack Switch from MicroHAM.

When I planned the 4 rotary HF towers in a square I had the idea that I would like to try to build a four squaere for 160m with the towers as radiator.
The towers are to short but with the capacitive head from the Yagi’s on top it should work fine.
I first tested an empty tower. Then I connected a coil at the bottom end tuned the tower to 1825 MHz very fast and easy. I also tuned the towers with an antenna at the top in the same way. Finaly I have tuned all the four towers. Now I know that I can realise this project.
To be continued.

We removed the SteppIR dipole for 40 meter from tower 6. This one will go to the 40 Meter tower. We also removed the 5 element Opdes yagi for maintenance.

On Sunday 22 September we lifted the 14 element C31XR on tower 6. The crew on the ground where: Jan PA0VAJ, Nap NA1NG, Thomas PA1M, and Peter PA4O. The crane I hired came from Drieborg.

The crane was just high enough.

The 3 meter high EME tower
The Mooobounce array was mounted on a 3 meter tower. This is high enough for moonbounce. The problem was that when mowing the lawn you always have to take care when you are driving around the tower. Second reason for the upgrade was that we are using the eme system also in terrestrial contests.
So I decided to upgrade the tower with a 3 meter tower section that I had still around from the building of the HF towers.
With help from Thomas PA1M I took the tower down. I took the head unit of and mounted the tower section. After that I mounted the head unit back to its position.
Now a challenging part was coming. Lifting the tower a bit so I could mount the yagis back to its position. I had mounted a winch on of my Versatowers to lift the tower. Peter PA4O had welded me a bench on which the tower could rest when I was working on it.

The winch would have to do a very hard job too put the tower on the bench so I had called a friend with a tractor to put it there.
Lifting the tower from the ground
The last part of the upgrade was to set the tower in the upright position.
Yagis o the tower
Thomas PA1M came to help to mount the yagis on the tower.

The next day I mounted the couplers and connected all the cables.
