i`ve divided the primary in 2 parts - one provides the coupling, the
other - tuning, separately and independently. so it`s possible to make
a hermetic container and fill it with the oil, but i don`t want to
deal with oil by now.

like Steve Conner said - nothing wrong with you - it`s with me, again :o)))
the trouble is - i`ve never faced the electric fields in the
dielectric, but i`ve had deals with magnetic ones in ferromagnetics, so
i decided mechanically that the field in dielectric would increase :-]
