Just like in coax chokes, you want to look at both the resistive and inductive 
properties - I would think that for PIM reduction, you want “lossy” rather than 
“high inductive Z”, but maybe high Z works, if it keeps the signal levels at 
the nonlinear junction low enough. 

As with a lot of this kind of thing, you’re probably looking at some 
experimentation, guided by theory.

Gene,
I saw a permeability of 250 @ 1 MHz on the tech data. It is 35 at 700 MHz
and goes down from there.

This link worked for me. Can't find application info for freqs below 700
MHz.
