摘要：
The invention relates to a dividing network in the support station in a radio telephone network, wherein the received multi-channel antenna signal (ANT) is divided among separate receivers (CH1-CHn) by means of a dividing unit. The dividing unit is made up of a filter (2), an amplifier (3) and a dividing network (1). According to the invention it has, in a cascade (11; 21), N directional couplers (H1-Hn; B1-Bn), there being branched out from the cascade in succession to each of the N receivers (CH1-CHn) a share, according to the coupling (k1-kn) of the directional coupler, of the filtered and amplified antenna signal (4).
