I now effectively use the extra coil to transfer high voltage (and displacement currents) without the impedance of the tesla coil itself.
It is done by using the extra coil as a high voltage capacitor plate.
the other plate is a parallel resonant coil with very high currents (tuned by large parallel capacitor to the same frequency)

remember Eric Dollard has said that modern equipment doesn't have the capability to output readings correctly because they don't account for these "unconventional" waves and impulses, so think deeply when taking readings. Cheers bro! I was hoping for a different video than this but I'll be waiting patiently!

Master ivo . I’ve been tuning my instrument for the last week. At times it sings the Moore’s lament, cohering me too longitudinal bliss: ) moments later it’s out of tune for a week. It is safe to say master ivo.......that u are one of the few, thank u . Try saying Nikola Tesla‘s name out loud, inhabit the current moment maybe express your gratitude.. your timing is divine.

I have patience. Major anticipation, yes, but patient none the less. The more you learn, the more I learn from you as you post video's. Everything I've seen you do with bifiler coils so far has given me ideas.

I have appreciated your thoughts and hard work on your journey, I just ordered the vector analyzer and if you could see it from others standpoints of how truly awesome you are in conveying these concepts I know we will get this, I know the ground is key, Tesla had some nice detail on the different pairings of impedance and capacitance to pump that ground. This may not be a helpful thought but I have felt like the final output has to operate with a set load. Looking forward to understanding this awesome problem!

Having quite a bit of experience with Tesla coils and radio systems and electrical engineering in general, I completely understand how hard that is going to be. Some of these tuned circuits are only going to work in about a 3KHz range. That's likely less resolution than your VNA, but at least the VNA is going to get you close.

Tesla knew the math. Too bad his notes are stashed away.

Ivo I agree, tuning is hard.
Tesla did check the weight of each coil.
If you think of the middle tap of a AC transformer. Why?
I think it's like the dielectric mid point on a bar magnet, electric does not flow like we think it flows. It's look like magnets rotating (tumbling) in a copper wire.
Hope this helps... Regards DC

Hai Ivo, doe je ding ! Als het makkelijk was had iemand het al gedaan . Volg je intuïtie met je kennis en kunde ik heb vertrouwen in je ! 👍

yeah so the third coil is basically to test the ambient field-currents created by the other two, and also to act as sort of a lightning rod for what would otherwise be energy losses, which is useful for all sorts of reasons

Question: im still novice. Please bear with me. The coils you created have a toriodal electromagnetic field. Dont magnetrons have that same fields in motion emanating from the center out?

Likely by now you have figured out things however... Essentially, you can take your 2 coil resonator and make that as your extra coil...
Then make a new secondary which is tightly coupled with the primary.
Same weight in copper as you know.
Just keep in mind the proportions required between a hammer and a bell...
To quote "a 1 oz, bell would be ill-served by a one ton hammer."

you are on right track and I m hoping you would get results through vna

From dollard's notes, the tesla coil and capacitor are at 4 times the resonant frequency between the secondary coil and the resonating capacitor

Did you see the presentation for the VNA for tesla coils available from conference this year? Sounds like it 😃

The vector network analysis is a pretty amazing tool thank you for sharing. I would like to see a analysis done on a LC tank circuit using the VNA

The key thing to look at is:
1 - the phase transition (phase crossing zero in a jagged line. This transition is the series mode, or normal quarter-wave freq of an Extra coil.
The impedance at that value is the drive impedance of the coil.

2 - the magnitude of the impedance ( |Z| will have a peak 5-20% above the series resonance. This is the parallel mode or longitudinal mode or 'tesla' mode.

I'm just a bit ahead in the VNA field and would love to help if you're getting your feet wet.
