We calculate the flux and size ratio of radio emitting features moving in antiparallel directions at relativistic speeds, taking into account that the pattern we observe may move at a velocity different from the one of the emitting plasma. Both velocities can be determined in sources in which both the approaching and the receding features are observed. This is the case of the galactic superluminal source GRS 1915+105, for which the pattern speed (responsible for the apparent superluminal velocity) was found to be 0.92$c$. For this source we find that the velocity of the plasma is 0.73$c$. The found velocity helps decreasing the estimate of the associated kinetic power. Since intrinsically identical knots will be observed to have different sizes, high resolution radio observations of GRS 1915+105 will be a test for the proposed difference of the pattern and plasma velocities.
