Anyone know of any calculators which enable a user to get an approximation
of the Z range of an antenna tuner by feeding in the variable values ?

If you have MicroSmith, make the load equal to 50 ohms. Set up a
series C, a parallel L, and a series C that agrees with the values
in your antenna tuner and watch the Smith Chart as the values of C
and L are changed. It's pretty interesting to see.

You might have a look at RevLoad written by Jim Tonne, WB6BLD:

RevLoad takes the settings of the tuner components
the system (tuner) impedance (usually 50 ohms) and
the operating frequency to calculate the load impedance
being matched. It covers all tuner configurations,
T-net, pi-net, L-net. And, best of all, it's FREE.

Download and run in a few seconds programs T_TUNER and L_TUNER, from
website below.
