Hi Bruce,
but at first resonance (self resonance) the inductor has the highest
impedance that it will ever have (theoretically infinite impedance), which is
what you want in a bias-t...

You need to ensure that the coil/inductor doesn't have its first
resonance below 1575.42MHz for an L1 receiver, otherwise it isn't very
effective.
There are some wideband chokes with first resonances well above 10GHz
when mounted correctly.
