[Boatanchors] Link coupled output?

[StephenTetorka at cs.com]

I've seen all kinds of math and tuner 'devices' on the Internet associated 
with antenna tuner circuitry...great stuff.

I have yet to find anything that can take my estimated C1 and C2 capacitances 
and inductance value - based upon the variable capacitor's geometry and the 
variable inductor's geometry at the low SWR "match"- and provide some 
enlightening information on impedance at the input/output.

It would appear rather simple, to put a 50 ohm dummy load at the antenna side 
- adj. for low SWR - and calculate the input ( transmitter ) impedance 
knowing C1, C2 and L values. - right?

Or visa versa..knowing that our contemporary rigs are designed for 50 
ohms...one can just as easily? know the antenna-side impedance at the shack.

Am I missing something in this thinking?
