Abstract
A method and a communications device are described, comprising a radio telephone ( ) with connected antenna path ( ) which can be used to locate precisely a defective area (F) in the antenna path ( ) in order to be able to repair the antenna path ( ) in a selective fashion. For this purpose, initially a wave with a starting frequency (f ) is coupled into the antenna path ( ), and the amplitude of the standing wave at an angular position is measured. Then, the frequency of the wave is increased until a corresponding amplitude is detected at the same angular position. From the frequencies present then and from a reading (n) which indicates how often the corresponding amplitude has been obtained, the fault interval (Ed) between the detector ( ) and defective area (F) is then calculated.
