This is new ground so I do not want to nickel and dime it to death until I have more experience under my belt. Present dish education is heavily weighted to phase methods used in planar designs or alternatively solely on VHF, the later being slanted designs via pitch and other factors that do not apply in my case. since my design evolves around equilibrium . I would also point out that some of Kraus's work is being thrashed with respect to gain and may well extend to use of deductions instead of observables which was heavily used in empirical gains with respect to pitch angles. Bottom line at the moment is that the antenna for top band be light and small enough for me to handle on the towerand on the ground without the need for me use my prop pitch rotor, which by itself is a handfull or to call for additional help. If I can't handle it alone then it defeats my original object with respect to small antennas without the normal compromises with respect to electrical wavelength. That ofcourse does not rule out diode action in the short run with respect to poultry fence mesh as a reflector. Regards Art |

Regards Art It would seem to me, there are but two ways to couple to the ether, either capacitively or inductively, if such is even possible (there could be "something else", who knows?)

I see other antennas emphasizing e and h fields and all sorts of stuff in between. I don't emphasize inductive coupling, at least not with what I am messing with now! Inductive coupling infers planar antennas acting solely on intercoupling of elements while at the same time ignoring the edict of equilibrium that goes with all laws of science such that the effects of the "weak force" are ignored. With inter coupling of elements you only get approximations as the last element of any array reradiates half of that which it receives. Thus the array always needs another element regardles of the number used to obtain maximum radiation. In the case of array in equilibrium you always reach finality with respect to radiation. All very simple. On the other hand this 477 ohms figure certainly is mystical to me, what is the point you are trying to make? Is it possible that the figure you are using is bigger than you intended by being larger than life itself In all this mumbo-jumbo something may, indeed, exist ... to date, "I just don't get it" . I will take a wild guess here and assume there is some connection to the aether which is eternally on your mind. Well John for equilibrium the aether is contained within an arbitrary border. That means that all forces add up to zero, a simple concept of Newton which also means that the contents are not nothing or a vacuum what ever that is in celestial terms otherwise the border collapses. You must also realize that what is within the border must be in a state of spin as well as being in equilibrium where spin requires the present of matter. So now you have a basis on which one can define the Aether which is something other than nothing or a vacuum. Knowing that particles flow thu this that is surrounded by an arbitrary border one could possibly state that for every addition of a transient particle another particle must leave and since particles atract or repel that which is in circulation in spin form must in fact be cluster form of particles. So John let your mind have a smidgeon of freedom accepting what is known and put things together the best way you can so that you have a datum line to build on or change as knoweledge increases which allows the addition of logic by the removal of past theoretical assemblies. All the above is material that you can use in your determination if I am of sane mind or not. But first you must set your mind free accepting only that which you can personally derive from first principles as something that can be built upon. Brrrrr it is geting cold Goodnight Art ...
