You might have done that correctly. I would admit that the first design does not look like one I would use and, IIRC, was designed for higher frequency.


The last link I think has a better design, and I would probably add more elements to whatever I was building since performance/cost is high.


I also am a fan of open air coil inductors, maybe just for their cost and simplicity, but they do present other types of difficulties.


Orienting the inductors will certainly help, or will it? It would be worth looking at the EMF, but I'd still want to shield each inductor.
