New program LINE_ZIN, for given frequency and load impedance, for balanced-twin lines, calculates -
Impedance Zo Input impedance, R+jX Attenuation, dB Power efficiency % Loss with standing waves, dB Reflection coefficient Angle of refl.coeff. SWR at load end SWR at input end
Input data can be varied in small increments from the keyboard to observe how a line behaves. Practical and educational.
