A 75m Texas Bugcatcher loading coil certainly
qualifies as a distributed load being about
1/8WL long.

Aw come on Cecil
It is a lumped load which is unbalanced and Maxwell demands
equilibrium ie balanced. Yes, it has distributed loading but formed
into a helix antenna
such that it includes lumped loading. Maxwell in his search for
maximum efficiency he would have added a symbol to his equations for
lumped loads . He then would have to include pitch and the like but he
just did not consider it as a consideration.
This is clearly shown with a WL verticle when for maximum effeiciency
it is tipped from right angles to the Earth ala the Corriolis effect
with which you are tampering with
when current rotates, and its introduction of a slow wave and a
different velocity factor
This is why you cannot equate lumped loads with antenna degrees, only
approximate
I have no which to debate it so I will leave it at that. Soon I will
be heading home.
No offense intended but physics is physics
