Ron,
There are 2 types of both networks (lowpass and highpass).
*C-L-C Pi* is a lowpass with the ability to ground one side of the
capacitors
*L-C-L Pi* is a highpass with both sides of the capacitors hot
*C-L-C Tee* is a highpass with both sides of the capacitors hot and this
is the common Tee tuner topology
*L-C-L Tee* is a lowpass with the ability to ground one side of the
capacitor

Another reason I suspect is the C-L-C pi network allows both the
variable
capacitor rotors to be at ground potential. This lets the shaft be at
ground potential making for a safer control that is not affected by the
proximity of the human operator's hand. No insulated shaft required
either!
I am having a lot of trouble visualizing a C-L-C (usually called a
"T" not a Pi)
network where any part of either capacitor is grounded, please explain
more.
