It can be seen that a fixed radfiator hasd a primary frequency and then some harmonic frequencies. The spacing and the resonant points of an antenna resides in the amount of resistance in the cuircuit from zero upto a critical point as with a tank circuit. This resistance value has the action of bringing the radiator vibrational amplitude to zero where it then takes of to a diminishing value compared to other componenents in the circuit to the point that where the radiator is resonant the contained resistance has negnigable effect. Thus one can make a folded dipole with a variable resistance in the radfiating circuit such that the main resonant point can be determined as well as the spacing between the harmonic frequencies. In addition, if the radiator consists of increased induntance designs such as contra windings then the distance between the resonance point and the harmonic points begin to decrease. Thus using the above one can now make a all band antenna where the resonance points line up with the desired frequencies. An easy way to accomplish this is to wind wire on a dielectris from end to end and back again several times until one has wound at least two wave lengths on the former and then feeding the arrangement at the beginning and ending wire points. Using a mfj 259 one can then determine the spacings of the resonant point by stretching the windins as well as adding the required variable resister. Note. the resistance absorbs the energy between resonance points and diminishes in effect as the point of resonance is aproached. For more understanding of the radiation format of radiators review the circumstances of voltage overshoot with respect to tank circuits The above will provide an alternate discussion thread that will take away the current tunnel vision aproach with respect to "black boxes" and bring the newsgroup back to the advancement of antenna techniques if it is that that peeks one's interests. By the way, it is the ELECTROMAGNETIC field that launches the particles from the radiating surface and it is the MECHANICAL REACTIVE FORCE that provides the mechanical resonance of the radiator *WHICH JOINS THE THEORIES OF NEWTON AND . MAXWELL that Einstein struggled for in vain. Somebody has beat you to it. Theories, like advice, are free so they exist everywhere. At least this one has some math (though fallacious) behind it: See: http://www.allanstime.com/UFT_private/final2.htm The Fundamental Field Equation The following equation is fundamental in understanding how the force fields interact and come together for this new unified field theory: D = (E/c*G)/A2* where D is the relativistic density, E is the energy of the unified field, c is the velocity of light, G is the universal gravitational constant, and the last part of the equation, / A2*, will be explained below. D and E are tensors with eigenvalues and quantum states associated therewith. *"A2" should read "capital Pi, sub-2" Density Dependence, D The density D is the dependent variable; changes in the energy (energy flow in and out of a region) cause changes in the density. For example, the energy flow to and/or away from any space-time continuum along the diallel lines determines the corresponding change in the density in that space-time continuum. Appreciating the energy field at the particle as well as in a region is central to the understanding of this theory. The energy can come from any of the force fields. For example, both equations apply: E = mc2, where m is the relativistic mass and E = hv, where "h" is Planck's constant "v" is the electromagnetic frequency of the photon. Energy can come from the other force fields as well. Later we will see some spectacular and very important examples of this interplay of the force fields. Parallel Component (A2) A dimensional analysis of the above equation reveals that A2 has dimensions of length, time and mass as the force fields interact. The forward slash "/" denotes being parallel in the unified field theory's mass-space-time continuum along the local diallel lines. The "sub-2" on the "A" denotes the energy coming in or going out in the mass-space- time continuum along the diallel lines in the local environment or region. Combining the energy with this term we have E/Pi2. Hence, we see that this denotes the energy per mass, per length and per time taken in the parallel direction of the local diallel lines. The quantity in the denominator of equation(1), cG, is the normalizing factor, so that the dependent variable, D, is the density factor taken in the parallel direction of the diallel lines. It is the density that is the principal resultant output after combining the energy from the force fields. Since the subscript "sub-2" denotes the energy from all sources coming into or going out of the local environment or region, a "sub-1" is implied for the energy, E, and the resulting density, D, as the recipients of the net energy coming in along the diallel lines into the environment or region. |
