Whats up with that spider looking coil?  Havnt seen that yet, have we?

Are you saying that the devices output was 220 vac 50 Hz/60 Hz
if so it requires an ac source in the device.As to the ground playing any part
I think that's a trick by TK,that part needs to be explored more,the common belief here is its a Tesla invention.
I don't think its a Tesla invention.

Has anyone that has seen the device measured the output?

I recall that Frolov had a clamp meter in one of the demonstrations and will go back and see if I can find that.  It was the green box video.

Again I'm aksing if there is at least the possibility that unilateral induction is a key element in the tk device. I'm totally fascinated by what zeitmaschine posted here 3 pages ago and I believe that this is also the function of  jack noskills device because of his counter bifilar coil arrangement...

LF induction receiver must be tuned precisely but any scopemeter with a 3D search coil (three or two coils wound with many turns of thin wire) concealed in the pocket would detect AC magnetic fields present in the room, regardless of their frequency.
The search coil could look like this:

You are right about the search coil, that is a good idea and can be made very small and would be the ideal antenna for a spectrum analyzer.

You are not right about the need for precise tuning of the receiver. At least in my system, there is a broad range of tolerance for the receiving capacitor and the receiving loop. The most power can be transferred at precise tunings of course .... but a lot can still be transferred even if you are off-peak, as long as the match isn't too bad, and with a couple of easily-changed receiver loops of different lengths a very broad range of possible frequencies can be accommodated. It takes less than a minute with a small screwdriver to switch receiving loops in my system.

IF such a system is being used, its transmission frequency cannot be too low, or everything metal will pick it up and get warm. It cannot be too high or the RF radiation will be powerful and easily detectable on simple shortwave radio receivers nearby. If I suspected RF or magnetic induction shenanigans, a low frequency RF spectrum analyzer would be the instrument of choice that I would bring along with me.
But from what I've read, nobody with such an instrument would ever be able to get close enough to a Kapanadze demonstration to use it.
