Today I have built the boxes with the relays for turning the towers and the box with the U links in the cabinet in the field.
Near the north west tower I installed two closets. In here I will mount the double ten switches from Microham and the switching relays for the four towers to let them turn left and right.
I got these nice boxes from a friendly ham who works at the local county. They were not used anymore and would be would be discarded.
I builded a cable box half way from the house (shack) to the towers. Now it is easier to get new cables to the shack and the field.
