Problems with the karlock system on the NN4ZZ tiltplate

This is how it should be

 This is how it was...

The karlock hook went into security modus while tilting down the tower.
This is not the expected result.  The hook must be released from the tower.

Frustrating, it must have been a millimeter game, but each time the system went into security modus in stead of tilting horizontally.   The wind played a role and also the weight of the cabling I suppose.

I was lucky to had this system on a Steppir, so I was able to lower the system using the previous way by shorting the elements.   Nevertheless, I retried with some extra wiring in order to unterstand what was really going on and how to solve it.

It seemed that the antenna wasn't 100 percent horizontal fixed on the mounting plate, quite difficult to have this correct because the plate isn't in a 90 degree status on the vertical tower.   There was a but more weight on the left side of the antenna and so the plate wasn't stable when lowering.

I did some extra work to have it better fixed and gave more space to the locking system.
Let's hope this time it will be ok.

I do not dare to think how to solve this with a big 2 element 40m yagi installed if this happens...
