Finally got this right. Well kind of. I need to add some capacitance out of it to bring it onto 40m because my inductors were a lower value than i thought I wound them at. But other than that, the shape looks fine and very low insertion loss.
As designed but using the incorrect inductance values.
This is the baseline, i still have not worked out how to reference things back to 0db.
Gerber files for the PCB Boards: bpf_singles
A quick update. Im happy with that. Shape is fine, low side attenuation is good and will kill any AM broadcast.
