Abstract: A motorized window treatment may comprise an antenna that allows for wireless communication. The motorized window treatment may comprise a roller tube, a motor drive unit, and at least one mounting bracket. The roller tube may be configured to windingly receive a flexible material and to be rotated to raise and lower the flexible material. The mounting bracket may be configured to support a bearing assembly of the motor drive unit to allow the roller tube to rotate with respect to the mounting bracket. The bearing assembly may be located between the roller tube and the mounting bracket, so as to form a gap between the roller tube and the mounting bracket. The antenna may comprise an electrical conductor wrapped around the motor drive unit adjacent to the gap between the roller tube and the mounting bracket.

Abstract: A motor drive unit for a system for raising and lowering a covering material (e.g., a window treatment system) may be configured to execute a test procedure for determining if the system is spring-balanced properly. The motor drive unit may be powered from at least one battery. The system may comprise one or more lift assistance springs configured to provide variable lift assistance to the motor drive unit for raising and lowering the covering material. During the test procedure, the motor drive unit may be configured to control the covering material between a lowered position and a raised position and determine a magnitude of an input power of the motor drive unit during the movement. The motor drive unit may determine that the system requires more or less lift assistance springs based on the input power, and communicate an indication that the system requires more or less lift assistance springs.
