ABSTRACT:
Rotary positioning of an antenna is provided from a remote control apparatus using a first reversible motor at the antenna and a second reversible motor at the control. A rotary switch at the control is coupled mechanically and electrically to the control motor such that movement of the rotary switch energizes both the antenna and control motors, which have substantially identical speed characteristics. When the antenna has attained the desired position, the system de-energizes itself. Mechanical resistance to movement of the antenna is simulated by a feedback motor mechanically coupled to the control motor and electrically connected in series with the antenna motor. The system contemplates use of direct current motors and a two wire connection between the antenna and the remote control apparatus.
