Oh yes, the important spacing--we agree on that alright (the rest too--I see
that physical/electrical length as important to--but "electrical length" and
"magnetic field shape" are related on an almost linear scale), but what is
"in" that "spacing"--now there is the nut of this... that "magnetic field"
is not a "proton projection" and my antenna does not "glow"--and that
"space" ain't no wire--or is it?

Warmest regards,
John

| JS Well, everything stated may be true... but I have never seen a beam

| JS size... if in doubt and you wish to confirm this--just look up!

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