Hi Richard, Could you describe the idea behind a 1/4 wave line inductor? I haven't heard of it before. My understanding is that the ferrite bead idea starts to appear as a frequency based resistor rather than an inductor at frequencies above several 100 MHz. It appears that the equivalent resistance will be several 100 ohms at GPS frequencies. I'm not sure that is really what I need ... Do I need to worry about self resonance if I am well above the resonance frequency? Thanks for your other suggestions.
