In the textbooks, a capacity hat is shown as having a capacity down

based on the physical dimensions, the resulting capacitance is so small
as to be meaningless.
So, .... what is the real picture here?
Abraham Lincoln often wore a large capacity hat. :/
This one ?

I once made an Abe Lincoln for 23cm as prototype for a beacon
