In what units are the wavelength scales on a Smith chart calibrated?
In fractions of transmission line electrical frequency
In fractions of transmission line electrical wavelength✓Ճիշտ պատասխան
In fractions of antenna electrical wavelength
In fractions of antenna electrical frequency

One complete trip around the rim of the chart corresponds to moving half a wavelength along the line, so the rim scales are graduated in fractions of a wavelength as it exists inside that line. Because the line's velocity factor shortens the wavelength, these are not free-space or antenna wavelengths.
