? The inductance will change with frequency. I use the Smith chart and the resistance and inductance are displayed at the marker frequency.

The inductance won¡¯t change with frequency (to a first order approximation and especially over a somewhat narrow range).
What will change is the reactance with respect to frequency.
XL= 2*pi*F*L
XC= 1/(2*pi*F*C)
The L and C values shown by the marker is calculated by solving for those values at a specific frequency (where the marker is set to)
