Bruce MICRO 1690/1700, you have for the first time given me a usable idea of what a so-called “capacitance hat” amounts to.
Your illustration of a spoke pointing, say, east, and an opposite spoke pointing west whose RF energy would exactly cancel out makes it clear that what we have is an upside-down “L” where the leg is VERTICAL and the little stub up-top is TRUNCATED-HORIZONTAL.
There is a design I’ve seen promoted (Star-H) for full-power situations in cases where great height is not an option. There are four poles set close together, with a total of 4-vertical wires up each pole, 45-feet, then each vertical goes horizontal at the top pointing east/west/north/south, out to the quarter-wavelength per each wire. It never occurred to me before, but now I am inclined to see the horizontal lengths on top as fully canceling each other out.
I’m now thinking the “capacitance” idea is mythical, like one hand clapping.
