Well it can be tall as long as the primary is also taller to match 
can't it? There is an infinity of configurations which can get to a 
coupling constant of 0.6 isn't there?

Which is effectively just a piece of wire at TC frequencies (bearing 
the operating wavelength in mind). I am aware of the coupling issue. 
Bearing that in mind, it is instructive to measure coupling to the 
primary at the bottom and top of the resonator in a conventional 2-
coil system.
    Again I appeal for some direct evidence that a magnifier can 
produce longer sparks than a conventional 2-coil for the same power 
input together with a reasoned argument as to why. I have seen no 
evidence to support this in my own work and I would be delighted to 
be shown how to do it.
