Hi Walt,

Most everyone has directly expressed complete agreement with that
idea.

Here's the recurring theme:

reflections.********

OK Jim, if that's so, then I've got to figure out a new way to explain how antenna radiation patterns are
modified by changing the relative phase of the signals fed to multiple radiators, and by changing the spacing
between the radiators. Looks like I've had it all wrong for lo these many years. I thought I've been reading
the same references as all the other posters.
