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. Regards Art |
