The design of the elements is interesting though. I wonder if
the curved elements - which you notice do not touch the
mast - are a synthetic (light weight - low windage) sphere with
similar capacitance, or whether the capacitance to the mast lower down
reduces the effectiveness? I think I would have put it the other way up.

a PCB layout for it. If you want one, I will make it for you since I recall
I owe you a favour....
