Multifrequency radio observations of NGC 4869 (5C4.81), previously reported by Dallacasa et al. (1989), are analyzed with an emphasis on the source structure and the orbit of NGC 4869 around the giant elliptical galaxy NGC 4874. The data are presented in tables, graphs, and contour maps and discussed in detail. It is found that the tail of the radio source is in equilibrium with the ambient medium, serving as a signature for the past (Keplerian) orbital motion of the galaxy, and is characterized by oscillations in its transverse size and in the position of the maximum-brightness ridge. The presence of a significant amount of thermal plasma within the low-brightness tail is inferred.
