When modelling close spaced element antenma
assemblies it is possible that some elements are
physically longer than the "driven" element.
Is the length of a element sufficient enough to
declare that element a " reflector" or are there
other caveates involved.( i.e. phase)
As background to this question I would point
out that that it is possible to have two closed
spaced (positioned) elements one of which is
shorter and one of which is longer than
the "driven " element, this combination being
placed either forward or to the rear of the
"driven " element.
