With an L network you have only two variables, the inductor and the capacitor. The goal is to transform the impedance of the load to 50 ohms resistive. The load can be described with just two values (at a given frequency), such as resistance and reactance. (There are a lot of possible ways to describe the load, whichever way you choose to use requires only two values to describe it at a single frequency) You want to find the settings of the two variables which solve the equation. With an L network there is exactly one combination of those two variables that solves the equation. With a Pi network or a T network you have three variables. With three variables, there are an infinite number of possible combinations that can solve the equation. All of theses solutions will result in a 50 ohm resistive load seen by the source, yet they may also result in unreasonable currents or voltages in the network DE N6KB _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec ```
