Nick you could justmake your device 1/2 wave instead of 1/4 wave or use a car battery as a your earth or some large metalic structure.

I think earth ground is used with a length of wire because it
has a consistent impedance.  Once we have something running
with an earth ground that is quite robust, then I think switching
to something else might be practical.  For now, a non earth
grounded system is out of scope.

Just as a reminder, you saw the differences apecore documented
by just putting some loops in his ground wire, it definitely appeared
to have a sweet spot with six loops.

A 40 meter grenade coil wound with 10 AWG wire has a resistance
of only 0.131 ohms.  At resonance the impedance should be near
zero and the wire resistance determines the Q factor.

We can get impedance changes due to most anything that knock us
completely out of whack.  For example, look at the bandwidth below.
That's how tight of tolerances we are dealing with.  You might also
notice the kind of power that is hiding in there, easily capable of
vaporizing the wire if the resonance didn't go to crap first.  Early on,
I wound a big grenade coil with AWG 4 wire.  I'm almost glad it
didn't work.  I probably wouldn't be here now if it had run for a
few microseconds before it made a crater.

One other thing...

Startup is a bitch if you are using lamps because the resistance
increases as the filament heats up.  This means your Q factor
drops once it's running.  A lower Q factor is easier to tune than
a high Q factor.  So at start-up, you have to be spot on frequency.
If you are not, you'll be playing Catch-22 forever, since the bulb
won't light.  Pretty sure this led to the hack Ruslan used by dumping
power from the push-pull into the load circuit--he had to get the
load active before the reactor would come into tolerance.

I would highly recommend using a fixed resistive load.  It will
need to handle some wattage.  Use something like a water
heater or oven core.  The more ohms the better for start-up
until you get things dialed in.  You can parallel a lamp to this
load as an indicator.  Whatever you do, you have to avoid
inrush current.  These systems aren't yet tweaked well enough
to deal with it.

Thanks for clarification, this load definition is as I understand one of the parametes what needs to be defined as a fixed value.

I d like to define other hardware specs if possible also.
One of these things is wire length of all coils and groundline.
Let me start with a propsal and if needed we can adjust... but more important we need to start with a reference setup.
Attached how I think the best coil/ wirelength setup should be configured.

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.
This means in my setup kachersecundaiy will have the remaining coillength in a separate coil.
Can i assume that the length of the kacher secondary is inclusive antenna and ferrite wirelength?

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.

  Yes, I could...But then, so can you.   You know that I don't just guess about what is needed, I leave that up to you guys.      One thing to keep in mind is that the ground line will show no gain if the device is NOT in resonance. So, you can tell when in resonance, if when connecting the earth ground to the device, it produces a gain at the output.  Geo's bulbs won't even light at all, without a proper ground line.
    Also, if your Kacher secondary is not tuned at the right frequency, your Kacher circuit controllers will not  make up for it.   So, if you want to try 2MHz, as the Kacher frequency match, the Kacher secondary needs to be tuned in wire length to that frequency, first.
   I would not believe what Ruslan was saying in those older videos. His interests are not in helping us out. But in making money, from this device sales instead. Even if it means selling a non working device, for $5.000.
No "secrets" will he provide us with.
