Abstract: A satellite transmission receiving antenna with unique mounting provisions for a recreational vehicle roof. A generally cylindrical collar extends upward from the vehicle roof and attaches to a load distributing panel under the collar and over the area of the vehicle roof for load distribution. A parabolic reflector is hinged along an edge to a generally horizontal turntable within the collar so that the reflector may be rotated to a concave downward position to act as a weather cover over the collar and also to provide smooth aerodynamic conditions during transport. Rotation of the turntable through a motor driven gear coupling to the turntable effects azimuth positioning of the antenna and elevation angle is set by a linear actuator.
