So Rich, are you saying that textbooks are incorrect?  As I thought more 
about this, I realized that purely reactive networks do indeed make one 
load look like another.  For example, we make a 3500 Ohm impedance of a 
tube look like 50 Ohms to our antenna.  We make an antenna of some 
impedance look like 50 Ohms with an LC matching network.  Same principle 
applies here.  I really would like to see your results on a Z analyzer 
because if you can prove it wrong, you've just thrown a good part of the 
current RF theory out the window.
