Graphical Solution of Voltage and Current Distribution and Impedance of Transmission Lines

On a radio transmission line with reflected waves, geometric construction is used to determine the voltage, current, and impedance at any required point for a known load of resistive or complex impedance. Unknown loads are determined by observation of standing waves and the use of geometric constructions. Charts are shown for the direct determination of voltage, current, and impedance vectors at all points on radio transmission lines for any load condition, for use in solving transmission problems.
