[Elecraft] Miniature self-supporting HF antennas

[David Gilbert]

I never said anything about base loading.  That's where most of the 
current is, and therefore the most opportune location to create loss.

There's no current at the end (top), of course, so a loading coil does 
no good at all there ... somewhere in between is generally best.
