We now have same wirelength for grenade and kachersecundairy.
In order to have the "0" node starting at groundrod position we totally need 3/4 total wirelength.
This results when using 37.5m groundline we need to add an extra 37.5 meter coil.

Probably adding an extra groundcoil mskes no sense... so can we conclude that having the 2Mhz grenade isnt a good option?
When we could have it resonate at 1Mhz we dont need the extra 37.5meter groundcoil.
Even the kacher secondary could be tuned ( by antenna) to 1Mhz if its wirelength is the same as the grenade.

  Do you think that the 37.5M grenade coil length as being the same or as good as any other length?
The inductor is 1/2 that size. Coincidence?...  My opinion, is the the length of the grenade output coil needs to tune to a natural ambient frequency peak, at that particular frequency. And, not just any old frequencies.Spacial coherence to the right Earth frequency, may have everything to do with it.

Well there are other inductorlength defined... Ruslan states 1/4.
I have it 1/3... 12.5meter it fits exactly 2 layers .

So its not a parameter from which we can say now its whatever.
Same as frequency... I have a Russian schematic were all loops are defined at 2Mhz...
28T pulses grenade with seriescap at 2Mhz
Both leads from grenade are connected to a 37.5meter groundline by a diode.
I dont know if it works but it gives some direction about m.o. in my opinion.

This is my 2Mhz inspiration9

The issue is that in order to get the kacher to resonate at 2Mhz i cant use the 37.5 meter completely in the secundairy coil.

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.
