Now the next thing we need to figure out is where are the
best places to inject our two input signals?

What is high voltage, low current?

How about low voltage, high current?

Doesn't matter does it.  Within the grenade coil it's just
a blob of moving energy.  It all depends on where we take
it out at, which will be on the open (voltage) end.  This end
isn't fully open though.  Our load is a partial shunt, so we
will have voltage and current there.

So now the trick.  The injection of two quite different sources
both in Voltage/Current ratio and frequencies.  What is a
Voltage/Current ratio?  Ohm's Law says that is a resistance.
Since we are dealing with AC signals with their respective
frequencies, we can call this an impedance.  What do we
know about transmission lines and impedance?  We know
if we want the energy to fully transfer, the impedances
have to match.  That means, the method we use determines
what the Voltage/Current ratio has to look like.  So at this
point we probably should assign impedance ratios to each
of our two input signals.  The output from our Tesla coil
is going to be a very high impedance and the output from
our push-pull will be much lower.

This is me just taking a wild stab at it, but I'm guessing
a capacitive coupling is the preferred method for high
impedance and magnetic coupling is probably more
suitable for low impedance.  We cannot directly connect
to this transmission line because neither of these two
input sources are going to have the same impedance
as our load, which is what sets the impedance for the
grenade coil.  Yes, the grenade coil's impedance has to
match the load, else any energy in there cannot be
extracted without loss.

Impedance works in general terms, but when we get
to the aligning the waves, overlaying them with their
respective frequencies, then I think we have to go back
to thinking resistance, voltage/current ratio.  Because
at that point when we examine instantaneous behavior,
we have to see differences in potential so we can predict
which way current will flow and what the ratio will do.
We will be looking for a gain function that forces energy
from the ground, into the grenade and out to our load.
I'd be willing to bet there is a voltage/current ratio between
the air and the ground that comes into play here.

Made a second vid after rewinding layer 6 from cw to ccw.
Which lowered the inductance from 80yH to 17uH.
Frequency increased from 1.78 to 2.3 Mhz approx.

During your sweep, I saw four or five points where you get a
nice clean spectrum with almost no harmonics or distortion.
Those are frequencies that are aligning within your grenade
coil exactly.

Where it is going to get interesting is when we bring in the
other input source and we start seeing some heterodyning.

Ok, quit interesting.
So i will look back tomorrow to see what frequency that is.

Yes, lets see if we can brimg it a step further
If you have any suggestions, let me know

So for my understanding, second source comes from inductor? Right
So we should puls inductor coil at same time as we do now with antenna?

I guess we take the frequency as you noticed, same time at antenna with determind grenade frequency?

For now, just inductor alone.  I'll be quite curious if the
frequency sweeps hit the same points or not.  You'll have
to let us know how you hooked things up to make it work
since the inductor really isn't designed for high frequency
input.  If you can't get any good signal going, don't be
alarmed.
