Probably the very thing you need. A sort of RF network / impedance calculator

I've used an ancient DOS version of this for years. And, personally still prefer that one - but it is all windozised now

I am experimenting with various forms of matching network to go between my 136kHz antenna and the transmitter. It would be very handy if I had a fairly simple circuit analysis program with which to do the following:

Having measured the input impedance to the combined matching unit and antenna, then “subtract” the components of the matching network, see what I get and compare it with what I actually measure. I'm not always convinced that what I measure is what I think I'm measuring.

Platforms available: XP, Linux and MacOs X.

Yes, I could write something, but somebody must have done this and there is no point in reinventing the wheel.

Any suggestions, please?
