If you do the above, does this make the frequency above or below 2 MHz?
Guessing below...?

I'm asking because it appears to me you guys are overlooking
interwinding capacitance.  A tightly wound coil will resonate at
a lower frequency and have a lower Q factor--the capacitance
will be higher.

For the Tesla coil using enamel wire there's a trick I used
to reduce the capacitance and get the frequency higher.  That
trick is to increase the spacing between turns.  What I did is
wind the coil with two wires--one was actual enamel wire
and the other wasn't wire, it was clear fishing line which gave
me a nice consistent spacing between the conductors.  Doing
this, the resonant frequency went way up, giving me the option
to add more turns.  If you overshoot in frequency, you can pull
some turns of fishing line off and pack the enamel wire back
together.  With several iterations, you can dial it in pretty darn
close.

Thats what Im saying.
Have it coiled, and gets at 1.4Mhz

W/o fishingline

At 1.4MHz now, I'd bet if half of your coil had some spacing, you
would bring the frequency up pretty close to 2 MHz.

Ok,.. i will try it tomorrow, have some 25/100 mm fishingwire

   Ape:   I don't trust anything that Ruslan has said.   Stalker, on the other hand shows and explains every thing in detail.  If the post above is true, where does the 3 turn coil, and it's 1/2 size grenade inductor coil connected with an in series 0.47uf wima capacitor comes into play? 
I am not sure which device you are quoting from.
As Ruslan has not shown any scope shot showing 2MHz, or 2KHz. But, he has shown a 15KHz scope shot. If my memory is correct.
But, remember that every self runner is running at totally different frequencies.      I am referring the TopRuslan 7 device,  that we had built some years ago.

   P S.  Frequency error has been corrected to 15KHz, not 1.5KHz.

you would need to use fishing line. you realy need to find the wave length your using if its.37.5 mtrs you need to devide it by 1/4 wave thus winding it over 9.375 cm would be or 18.75 cm would be in resonance, other wise you get jumps in frequency
when tuning and losses. just like ham radio.

The other thing is 37.5 isn't in tune with the univers

Thinking about it if i were you why bother just go wild, oh you have !
