Default circular radiation!

I have just completed at least 50 hours of modelling a coil where an
assembly was made of half coils and the relative positions of such were
altered by raising or lowering the half coils which thus introduced vertical
connecting pieces between the half coils. In addition to the above the half
coils were wound CW and CCW in turn This arrangement was fed at the bottom
in vertical style.
Unlike other modelling I took great care to ensure max use of segments
together with the use of computor variable dimensions when seeking max
radiation,impedance and all that.
What I found was as follows:
The phases of the current stayed relatively constant EXCEPT it consisted of
two phases opposing each other.
The manipulation of the coil positions retarded rapid changes in impedance
( I see this as a consequence of reducing reactive components that one has
with a normal
coiled load)
No matter what changes I made( I never changed the diameter of the coil but
did change the diameter of the coil wire e.t.c) I was never able to obtain
characteristics of a normal whip.
From the above one can deduce that removal of reactance from a structure
brings it closer to a dummy load.
On the question that I was fussing about i.e. dust generated as a dust cloud
in straight and curved travel
represents losses per Newtons law of action and reaction.
the dust portraying the reactive forces to radiation.
So I found out for myself what everybody already had accepted as fact. So
now another silly question which I only pose to myself..Interchange of
energy between reactances are understood but what does overshoot of energy
between reactances do, create heat or radiation?
The energy held by the overshoot is now of opposite phase to its original
destination !
No I am not starting another thread, just explaining the modeling that I did
in my relearning proces for all to share.

I think the opposing coils caused a temporal rift in the space-time
continuim - because I would swear I've seen this subject before - or is it
deja-vue?

I really do not know Hal as it all was a surprise to me.
I wanted to believe that the lack of phase change would keep radiation at a
peak without thinking of a possible constant weak radiation. It also
surprised me that there appeared no current curve that one associates with a
whip which makes one wonder about the cancellation of reactances along a
radiator and leaving just resistance.
Proff Underhill stated last month in RADCOM (U.K.) that a lot about loops is
unknown which I find obvious as some in this group view mutual coupling as
following the same rules of very close coupling not realising that the
inductance inside a coil is a world of difference to that from coupling
outside of the coil. One esteemed member of this group stated that there is
no mechanical pump type thing in radiation when I pointed out the function
of a loop/phase change action in the combination loop dipole arrangement. I
sure hope that the experimentors of tomorrow are not discouraged by those
who are prisoners of yesterday

Are you trying to make an antenna outa those coils?

check one: ____ yes ____no

if so, does it work?

check one ___yes ___no
