H/D ratio

["Tesla list" <tesla-at-pupman-dot-com>]

I found on the net in a few places stating that the maximum amount of 
inductance from a coil is when the height is the same as the 
diameter.  This is a 1:1 ratio.

If that is the best inductance ratio then why is this ratio not used for 
the tesla coil secondary to take advantage of a high inductance ratio 
between the primary and secondary?
