In a communications system including a base station coupled to a transmission antenna by means of a transmission feeder cable, and coupled to a receiving antenna by means of a receiving feeder cable, a method and system for testing the antennas and feeder cables includes a testing apparatus located at or near the antenna end of the feeder cables. A processor located within the testing apparatus initiates tests in response to commands received from the base station by means of a digital interface, which preferably uses one or both feeder cables as a communications medium. The testing apparatus includes directional couplers for each of the feeder cables, and corresponding power detectors for measuring both forward (incident) and reverse (reflected) power. All test results may be sent back to the base station, by means of the digital interface, for further analysis and status reporting. |
