A stabilizing mechanism and method for a reflector antenna, in a mobile satellite system on a transport, such as a vehicle, for substantially minimizing damage to the reflector antenna when stowed. The stabilizing mechanism uses a stabilizing surface and a pair of stabilizing devices connected on opposite sides of the reflector antenna to provide a pre-load separation distance between a stabilizing surface and the reflector antenna when the reflector antenna is stowed. The pre-loaded separation minimizes any movement of the reflector antenna towards the stabilizing surface during movement of the transport or in adverse environmental conditions.
