I implemented the 6-el OWA for 15 m project at the same time as the 7-el monobander OWA for 20 m
Here you will find photos related to this antenna.

I prepared the material for the mast and found this here the next day.

During ARRL CW, I extended the tower a little using a crank handle—the motor drive wasn't working because it was very cold.

And this is the full height.

Two months later, I finished cabling so that the antenna could be rotated through its full range. And I aligned it exactly with the Moxon above it :-)
