Abstract Preceding papers were concerned with the principles of a wave propagation experiment, which appeared suitable for a simultaneous determination of electron concentration Ne and electron collision frequency v in a magnetoplasma. The complex wave polarization was used being defined by field strength ratios. In former model calculations the electron concentration profile was characterized by exclusively positive height gradients. In this paper considerations are extended to an electron concentration profile with gradient inversion. Calculations on error propagation and wave damping and an estimation of the coupling parameter do not lead to new or serious restrictions in the question of the applicability of the method.
