OK now on my computer A gamma match is the following A sort of folded dipole, performing an impedance step-up A parallel shorted transmission line stub, adding shunt inductance A series capacitance Below is the equivalent electrical circuit. Magnetic loops which is what part of my theory is based on, can be powered with a gamma match or another small loop or a coil wound on a ferrite core and the loop passing through the middle. There are also other ways such as using three capacitors were the two outer capacitors supply the impedance and the center cap is the LC resonator (the later you simulated for me and shows a large current in the loop). I hope soon to have some new equipment and will be building again, not easy with no equipment. The gamma match is more difficult to tune, it has a very narrow band width and will go out of tune easily. What I suggested above is a bit of a hybrid because it has capacitance to earth ground plane via the coil wound around the loop, which in turn finds it's way to your SG ground I would expect which is sitting on the bench un connected. If you had a magnetic loop antenna connected to a transmitter, and you put a single shorted loop of wire around the loop wire, the current in that wire would probably blow it if thin enough, or it would glow hot. The loop in this case could be COPPER and not iron, my dual theory on paper holds as a current loop and inductive core if it is iron. I have done tests on this and it holds correct. More needs to be done in this area, don't give up on the theory (antenna theory is also correct in practice, and more so). Regards Mike
