Deactivating a Pi-Antenna Tuner
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 Di Maria |

Position one connect to tuning elements. Position two connect to bypass. 73, Fred |
