However, when I build it, the best adjustment I could do is as per attached image. https://obrazki.elektroda.pl/3695947800_1456963361.jpg https://obrazki.elektroda.pl/8022947100_1456963363.jpg I tried to understand which parameters should be manipulated to obtain the same result, so I tried RFSim99 simulation as below https://obrazki.elektroda.pl/2973757800_1456963249.jpg Could someone tell me if this equivalent schematic is adequate?
