Ferrite Choke wiring, understanding the datasheet and how it affects the signal
This choke is part of an LC harmonic antenna resonant transmitter. With some effort characterizing the antenna, it can be improved but not with insufficient details on cable balun, Z antenna, and increasing resonant current while raising impedance and current to bandstop filter.  this is similar to blocking Class E PWM except inverted where you want the antenna resonant current to be radiated instead of blocked.
