In the "theoretical" portion of the presentation audience was told that current
across the helical coil decreases away from the feed point, while across
loading coil it stays constant.

I've often wondered at exactly what crossover point a helical coil
turns into a loading coil. If one adds a one inch stinger to a helical
coil, does that turn it into a loading coil? How about a one foot stinger?
Is a one foot long loading coil not a helical coil? Does a one foot long
loading coil really have less phase shift than a one foot long piece of
wire? On a center-loaded mobile antenna, how can the ARCCOS of the current
at the feedpoint be zero degrees and the ARCCOS of the current at the tip
be 90 degrees without there being 90 degrees between the feedpoint and the
tip? (When are you going to invite everyone over to Bar-B-Q that sacred cow?)
