Three rms values of sigma:sigman were considered to represent the geometrical quality of the surface for the evaluation of radio reflector surfaces. The effective rms-value sigmaTP represents the electrical quality of the reflector; this quantity and the corresponding surface weighting function must be taken into account in design calculations, adjustment procedures, and in comparisons with the radio gain measurements. The Effelsberg 100 m antenna is used as an example of a steep parabolic reflector.
