    摘要: A radio communications unit (121) that has a casing (122) includes an antenna (123) that is connected to a signal processing unit (125). A metal object (128) is placed in the casing (122) and connected to an impedance (130). The antenna (123) receives a radio signal (309) which has repeating fading moments where the signal strength C is exceedingly low. The signal processing unit (125) includes means for controlling switch means (129) and impedance unit (130). In their simplest form, these control devices are manual, although they may alternatively comprise devices (134, 135, 136) that are integrated in the signal processing unit (125) which controls the activation of the metal object (128) and the impedance (130) with control signals (S1, S2). When the antenna (123) is situated in a fading minimum, the metal object (128) is either connected to or disconnected from the impedance unit (130), resulting in new signal reflections that cause the fading minimum to be moved away from the antenna (123).
