Known is a low-power point-to-multipoint cellu- lar television transmission system (1) in which transmit- ter stations (T1, ..., T19), which are located in centres of cells (C1, ..., C19) of the system (1), comprise omni or quadrant-directional transmitting antennas transmitting to receiver stations (R1, ..., R8) located in the cells. The known system operates in the microwave band. Such a system architecture gives either rise to a transmitting antenna which is difficult to manufacture or in itself is rather complex and thus relatively expensive. A sys- tem architecture is provided which can be easily imple- mented and which avoids using omni directional anten- nas. To this end the transmitter stations (T1, ..., T19) are located at the circumference (CF) of their cells (C1, ..., C19) of the cellular sytem (1), and each transmitter station is provided with a directional antenna (TA1, ..., TA7) covering its cell. Preferably, the transmitting an- tennas (TA1, ..., TA7) in the system generally transmit along a main geographical axis (ax) of the system (1). Each program to be transmitted can be transmitted via a separate channel and a separate radiator (TA1a, TA1b, ..., TA1i). Then, the channels are completely indepen- dent to each other.
