It appears from looking at the PCB (Front and back), that the power rail goes straight through the inductor (2 points). The purpose of this circuit is to filter 1.2GHz noise on power rail. Instead of spending $15 on a pre-made one I would rather just get the proper inductors and do it myself :). If anyone can point me in the direction of figuring out what inductor would work for specific frequencies (And filter caps too), that would be awesome. I want to make one for 433mhz as well.
