In this video I'm looking to the nodes and anti nodes of flat pancake coils.
The first is a bifilar but center A is not connected to outer B like in the patend.
The second is just single wire coil.
I'm not sure I will be able to get the configuration so that node point will be located on the coil where I change winding direction.
I even don't know it's possible, but I will only know if we got the same situation as with normal coils where we do need to change winding direction when coil passes across node point to not create a situation where it fights itself.
I was surprised how far I could go with the single wire coil with an untuned receiver.
