Instability of steady-states of the plasma diode with inhomogeneous field without reflection from potential extrema are studied. It is shown that all considered solutions are unstable. We have also confirmed this result when simulating small perturbation evolution of a steady-state solution.. Keywords: plasma diode, electron and positron beams, solution stability, nonlinear oscillations.
