Hi
I have build an antenna tuner Pi (2 capacitors and at center a coil).
It works fine.
Now, i want to add some switches to activate or deactivate it.
Can you help me to understand where to connect these switches?


Thank you very much.

Giovanni-

Use one Double Pole, Double Throw Switch.

Connect switch Commons to input and output.

Position one connect to tuning elements.

Position two connect to bypass.
