Feed line impedances for various wire diameters

The following table shows the nominal characterstic impedance (Zc) of a ladder line constructed with Instant Ladder Line clip-on wire spreaders, for various wire diameters. Note: this is the diameter (i.e. not the surface) of the conductor and does not take into account the thickness of the insulation.
