Better solution is to wind multilayer coil (about 5 layers) on ferrite rod

or

to use tank capacitor bigger than 4.7nF. In this case you can use capacitor of 27nF and wind one layer on your 20cm ferrite rod with inductance of about 28.8mH.

or

instead of 4.7nF you can use C of 33nF and coil of 23,7mH.

AND IN THE THREE CASES, WE WILL HAVE THE SAME RESULT?

FIRST (Better solution is to wind multilayer coil (about 5 layers) on ferrite rod)

THEY IS BETTER?
