<< 
 Hi to All,
 
 
 Below are two given coils. 
 What is the frequency of each coil? Another coiler and I disagree on the
 resonant frequency of these two coils. Can somebody help?
 
 Coil A:
 21.7" long
 3" diameter
 Wound with 1230 feet AWG 28
 He says 418kHz (I say 200 kHz)
 
 Coil B
 10.84" long
 6" diameter
 Also wound with 1230 feet AWG 28
 He says 275kHz (I say 200 kHz)
 
 Who is right??
 
 Thanks,
 Reinhard

Reinhard,

Assuming the length given is the actual winding length and no top load, I
calculate 375 khz for the 3" dia. coil and 296 khz for the 6" dia. coil.
