electromagnetic wave fundamental frequency and harmonic series?

Hello, I am wondering about the frequency of output of my Tesla 
Coil.  I know that the EM wave radiates with a fundamental frequency 
of whatever your coil resonates at, but does it also exhibit 
harmonics as well?  for example, my coil resonates at 260kHz, so then 
would it be correct to say it radiates EM waves at 260kHz, then at 
conciderably less energy 520kHz, 1040 kHz, 2080 kHz, and continuing 
until all energy is absorbed?

Thanks for the help
