HELLO SL;  Maco probably will not help out with a copy of there antennas design, makes sense.


Those matching rings change two values of inductance and one value of capacitance.  At one time in adjustment. Not user friendly even with the proper antenna length. Wish I had the majic fix but I dont. You just have work with it with the antenna analyzer. Making antenna and matching ring length measurements and what frequency its on, and with time you will probably fix it. Then post results.
