Hi Hal
I'LL be happy to explain where I am coming from but this time I will try to explain my thoughts in a non technical way which may be seen as folksy which may well bring some caustic comments but I do owe it to all since I asked for help. First My aiim is to negate the onslaught of inductance and capacitance to ward off rapid changes in impedances Secondly I want to see what changes occur by using corregated material as radiators compared to smooth surfaces.. Now I will rerlate how my thought processes work even tho they may be totally out of whack but it will help to explain the terms I use. If one looks at an A.C. generator it can be seen that the shaft rotates at a constant speed and it helps to see this by attaching a ball on a string and tieing it to the shaft. The circular motion when looking at the shaft endwise makes the circular pattern very obvios. If however, you look at the shaft side ways on what you will see is a ball going up and down either siode of the shaft. If one moves the generator a short distance as the ball takes one revolution a sinosoidal; trace will be apparent arount the shaft axis which can be interprete by some as showing acceleration and deceleration of current even tho that hwich generates this trace or graph is rotating at a constant spoeed ( This being important because it may be synonamous to some as compared to the speed of light) Now let us look at another version of movement in that the generator instead of moving in a linear motion takes on a circular motion and where the rotary speed of the shaft still revolves at a constant speed. From this. we can say that the speed of energy along the radiator is still the same as in the first example ,but what is different? If the generator was moved forward in the fiirst instance there was an equal and opposite reaction force which can be seen as a cloud of dust as a car accelerates forward. In the second instance the car traveling around a circular course showers dust in a continual fashon away from the track even though it is proceding at a constant speed. If we try to generate a graph of current versus time the dust generated on a circular track is a constant i.e. then also the current level on the graph must also be a constant value. Now let us look at a current flow on a load on a antenna such as a coil which is hellicaly wound. We know that the phase will be constant around the first loop but in this case we have added inductance and capacitance by virtue of the close proximity of the next coil and the next coil e.t.c which varies the impedance along the wire and thus rapidly effects a movement away from a purely resistive impedance. This lead me into separating the coils from each other by juxtaposition so that inductances were not additive ( I reversed the coil direction as well as positioning them apart.) Since all these coils are connected in series one must hope for a intercoupling effect will bring the current down on these vertical portions in the event that radiation from them are of the correct choice, either additive or detractive. Thus the project is repeated from what I have done in the past only this time I am using numourus loops in the event that resulting antenna height will be eye opening as well as very broad banded. As a follow up the corregations on the loops will be removed by laying on the surfaces a flat adhesived back aluminum tape(Ihave no copper tape) To try and ascertain what changes occur by having a smooth surface radiator Well Hal there you have it, possibly to long, possibly everything is wrong and again possibly hopeless to understand but it the best I can do Regards Art "Hal Rosser" wrote in message ... Ok, so the acceleration is in the phase-shifting between the adjacent coils ? If I interpret that correctly, then its not a 'real' acceleration, but a simulated acceleration - much like using pulsating DC to generate simulated AC. If you could describe it in terms a normal dummy like myself could understand or at least draw a better picture, your theory may be taken more seriously. You say Roy's word is not good enough - But Roy has demonstrated his expertise in this area time and time again. I come here to learn from folks like Roy - and to inject some of my own thoughts from time to time. You come to the group asking for comments - and you got them. You did not speak in terms of technical details - so a reply using technical details may not be deserved. There is no disgrace in asking questions (like you said) - but rejecting expert opinions can be seen as a disgrace in some instances. " wrote in message news:dJeUc.269797$%_6.33856@attbi_s01... Hi Hal, nice to meet you What I have is not really a prposition or a legitimate theory, it is just |
