Kreso,

Usually they are equal in height.  Raising the secondary relative
to the primary will reduce the coupling.  The height relationships
do not tend to be too critical in a VTTC.  I've run them higher,
lower.... whatever works best.  It sometimes takes a lot of fiddling
with the adjustments of coupling, tuning, feedback, grid leak
resistance, etc., before best results are achieved.
