"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."

Walter`s systen isn`t broken so it shouldn`t be fixed. Signal strength
at a point in space depends on the vector totals of its constituents.
Walter`s totals are determined by positions of the radiators and phases
of the currents in those radiators.

Obviously, where vectors are in-phase they add and where they are
out-of-phase they subtract.

The system works, that`s why the FCC endorses it.
