Abstract

A motorized roller shade includes a shade tube, including an outer surface upon which a shade is attached, an inner surface defining an inner cavity and two end portions, a motor/controller unit, disposed within the shade tube inner cavity and mechanically coupled to the shade tube inner surface, including a support shaft configured to attach to a mounting bracket, and a DC motor having an output shaft coupled to the support shaft such that the output shaft and the support shaft do not rotate when the support shaft is attached to the mounting bracket. A wireless receiver is coupled to the motor/controller unit to receive wireless signals and an antenna is arranged on or in at least one of the two end portions.

Claims
