Abstract

A method verifies a completeness of an antenna disposed on a window. The antenna is electrically conductive and has a first end and a second end spaced from each other. The method comprises the step of placing the window on a fixture for supporting the window. The method also includes the steps of automatically aligning a distributing probe and the first end of the antenna and automatically aligning a receiving probe and the second end of the antenna. The method further includes the step of activating a current source to pass an electrical current from the distributing probe to the receiving probe through the antenna. The method also includes the step of indicating passage of the electrical current from the antenna to the receiving probe with the indicator to verify a completeness of the antenna.
