No one is saving face or conspiring against a new idea. You can`t break the laws of physics no matter how hard you try. Correct Please point to the particular law that I am breaking, that would really help out a lot Antenna performance is based on lengths of wire in the air and the currents in them. By performance you meam energy in vesus radiation out as with a closed arbitary border. Take a broadside array for example. It is usual to drive current through all the elements of a plane in the same phase so that the fields at a distant point perpendicular to the plane of the array are additive to make a large signal. It is a matter of radiator lengths and currents. That is for a radiator based around intercoupling of radiators not one based on radiation per unit length of radiator The "large" signal is a resuly of how the radiation is arranged. It does not create extra radiation it just removes radiation fro one arear to supplement radiation in other areas. It does not create more radiation per radiator unit length Now consider a small diameter coil as a radiator. A loop radiator or did you mean a coil? It is called an radial mode helix because radiation is radial (perpendicular to the axis of the coil). No. That is definitely not true! It has two extremes. If collapsed, the coil becomes a single loop. Wire stays the same length ala apples with apples If stretched to its maximum, the coil becomes a straight wire. Ok. still the same amount of wire If controlled so that the same magnitude and direction of current flows in all configurations, the straight-wire version of this coil should produce the greatest radiated field strength perpendicular to the coil axis in the far field. This doesn't radiate more per unit energy supplied. Ther is no total increase of radiation per energy put in. Hmm so now you are moving away from total radiation to a robbing Peter to pay Paul situation So your radiator is very lossy as much as it has gain, which adds up to total radiation per unit length You forgot to make your point. My antenna with the same wire length has the same radiation as yours does per unit length of radiator so in your casev some how the ratio root LC became smaller while the wire stayed the same lengthj! How did that happen? You are saying that a straight radiator produces more radiation per unit length than any other antenna that does not have a straight position such that the radiation per unit length reduces the efficiency of the radiator the ability of producing radiation. So this is where we part since for a given length in equilibrium root LC is always the same thus so is the radiation. Is this a law that I am violating? What does the law state? RH this is my last shot of trying to analyse what you are saying that leads to the demise of my antenna. Now be specific for once and respond to each which I have high ligted. And as a final comment describe how one helix antenna radiates more than two helix anteena made of opposite polarisation because you continue to suggest this despite the fact we have doubled the wire!. Let us come to finality with respect to what you have been pushing for the last decade, P.S I am in St Louis for a get away and it is to hot and humid to go out. Makes sense?
