Can I correct one common misunderstanding about low-pass L-network tuners.

The two network configurations (shunt C at the output, or shunt C at the 
input) do not correspond to Hi-Z and Lo-Z loads, despite the labelling 
you often see on the configuration switch. If you don't believe me take 
a look at a Smith Chart and see which areas need each configuration. As 
an example, a load of 2+j10 needs the shunt C across the load - that's 
the so-called "Hi-Z" configuration!
