We examine the convective characteristics of the resistive hose instability of a charged particle beam propagating in weakly ionized gas. We use a model which includes a plasma return current and a constant rate of plasma electrical conductivity production by the beam. When the spread mass model is adopted, the hose instability is shown, in all cases, to be convective in the beam frame, with the amplifying disturbances propagating from the beam head toward the beam tail, regardless of the amount of return current. The minimum speed of propagation for the amplifying disturbance is typically 1/3 to 1/2 of the group velocity associated with the maximum amplification rate. The implications of this result are explored.
