Two completely different mechanisms.
A Beverage achieves F/R by travelling wave
reinforcement along the wire and rejection
from the undesired direction (dissipated
in the termination resistor). K9AY, EWE,
Pennant/Flag are all basically variations
of small phased verticals (i.e. achieve
F/R like the traditional cardioid pattern of
a pair of phased verticals).
