Again,  just thinking about it, I THINK a pi would behave similarly to an
L. The  math is left as an exercise for the student.




A pi netowrk is basically two L networks back to back. It allows a larger  
span of impedance matching input to output than a single L or even a T, but  is 
more difficult to adjust than either. The L net is by far the easiest to  
adjust but yields only one fixed amount of phase angle delay or advance at any  
given match.
The T net yields a practical phase range of about 20 degrees up to 135  
degrees. The pi net can go a bit higher.
