Abstract
In the booster (20) of a cellular radio telephone (20) the diversity reception is arranged so that the quality, e.g. the level, of the received and amplified (Rx1, Rx2) signal is detected (A1, A2), the better signal is selected by a logic (DP), and the selected better signal is connected (SWb) to the connection (C1) of the cellular radio telephone's antenna cable (AC). The arrangement includes a circuit (TF, DP) for receiving timing information from the cellular radio telephone in order to synchronize the operation of the cellular radio telephone and the booster.
