Testing of automobile mounted antennas
A method and device provides for the testing and validation of a control module for receiving wireless data and communications utilizes a transmission line coupler mounted proximate the control module generates a signal that couples to an antenna of the control module. The control module produces a signal in response to coupling of the antenna with the signal produced by the transmission line coupler. The resulting signal is utilized to check, verify and validate operation of the control module.
