Calle-

I assume others are going to mention this, but as far as I understand
your heigth to diameter is out of porportion.  I can't offhand think of
what the H/D ratio is supposed to be, but someone will certianly let you
know.

To add to this - why is it important to have a particular H/D ratio? 
Does it have to do with attaining resonace between the secondary and
primary or what?
