Resonant Frequency



Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Esondrmn-at-aol-dot-com>

I just read a comment from Paul Nicholson about the self resonant frequency 
of a solenoid secondary being higher than the 1/4 wave frequency for the same 
length of wire in free space.  I would have guessed it would have been lower 
due to the added self capacitance of the solenoid secondary.  I just did some 
calcs on my 6.0" secondary.  The self resonant frequency is 263 khz.  The 
quarter wave frequency calculated for a 1604 foot long wire is 146 khz.  So 
why does this come out backwards from what I expected?
