Subject: 1/4 wavelength

I have a question about secondary windings. According to a chart I found
from Chris Hill, a 4" diameter secondary has 774 
feet of wire to make the coil.  However the given resonant frequency is 540
khz.  According to a different web page I found, 
the length of wire in a secondary should equal the 1/4 wavelength, which
for 540 khz is 454 feet.  what gives? Am I missing 
something here?  any info much appreciated.  markjons-at-bright-dot-net
