Oh, Yes. Absolutely. Notice that in my first example the position or 
location of the L and C are interchanged but their values are different. 
Yes, for a given location of the L and C you correctly state that there is 
only one set of values that provide the match.

One of the beauties of the L network is that we have a choice of values for 
the L and C depending on their location or position relative to each other. 
This makes it possible to choose the lowest loss configuration from the mix.
