ABSTRACT OF THE DISCLOSURE A method for reducing the risk of poor reception in a time multiplex radiocommunication system which includes at least one fixed station and at least one mobile station, when transmitting from one of the fixed stations to one of the mobile stations, as a result of the reflection of transmitted signals against different objects. Transmission is effected in the fixed station from two antennas (19, 20), each of which receives signals from a respective branch. The signals in the two branches have mutually the same frequency and the same information content, but the phase position of one signal in one branch is changed (13, 14) in time, e.g. by phase jumping, in relation to the phase position of the signal in the other branch. In this way, any so-called zero points which may be present are moved geographically, i.e. points with no or with low signal strength. More than two antennas can be used in the fixed station for transmitting signals whose phase positions all vary mutually in time.
