it's up to you to choose the coil according to your location , or depending on which band you intend to work on , you can not say give me the antenna characteristics

unless you want to work on the electric or static field, you connect a telescopic antenna or ionic chamber

I will give you a tip, if you want an electric or ionic field LRL, Franco or Zahori is better than

this one,

this circuit is good for VLF or LF of VHF, and each band has its configuration, I did all that, I'm

trying to save you time

Excellent scheme!!!!! But this will never find a phenomenon without additions, it is almost Meneiro who understood that topic of regeneration.
