Re: Tesla Coil RF Transmitter

Hi Miles,

Most early radios were basically Tesla coils.  At say 200kHz, the 1/4 
wavelength is 1230 feet.  If you put a 1230 foot antenna on your 
Tesla coil, it will transmit.  Although real transmitters are far 
better matched to the 50 ohm antenna load...  But the key is our 
coils have very poor transmitting properties due to being so small 
compared to the length of antenna needed for our frequencies of operation.

Cheers,

        Terry
