Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I am currently building up a lightning detector based on this website: http://www.techlib.com/electronics/lightningnew.htm

as the diagrams shows, the resonance tank included a 10mH inductor and a 10pF capacitor.

As I want to calculate the resonant frequency (using the formula f = 1/2pi*sqrt(LC)), the answer was 5Hz, which is far from the desired range (should be around 200kHz)

is there any mistake in my calculation or concept? Thanks for your help.
