What I find so intriguing is what the 'taper proponents' intend to do with
the 'taper' data when at last they have it in the form of numbers? Of what
use is it? Into what are the numbers inserted? What is the next stage in
the proposed modelling process?

Efiiciency of the loaded radiator is roughly proportional to the area under the
current curve along the radiator.
1. Placement of the loading coil can drastically affect that. (Base loaded vs.
Top Hat loaded)
2. When using loaded elements in multielement designs, the current distribution
and magnitude along the elements needs to be accounted for optimum design and
performance. It affects the inter element coupling, current flow in the
segments of the elements and how the modeling programs "see" it. Try loaded 3
el. 80m beam or 4 square. Programs that can do optimization (YO, AO, 4NEC2)
would give better results if they can deal with real current distribution
closely modeled.
Now it is up to those program authors that neglected proper modeling of the
current in the loading coils to iclude this feature and make their softy wares
better and reflect reality mo betta.
