Reg Says:
Knowledge of the current distribution along a loading coil has no practical use except to assist with drawing pictures of it in books and magazines. WROOOONG! Have you ever tried antenna shootouts? Cecil can enlighten you about the difference in efficiency and signal levels radiated by various configurations (bottom, center, top loading). The efficiency is proportional to the AREA under the current curve on the loaded radiator. That is dependent on the position of the loading element within the radiator. That also depends on the current distribution (drop :-) across the coil. Use that in the loaded parasitic element beams and the effect is magnified. So obvious, but hard to swallow for Rauchians?
