Monte Ceneri transmitter

Geschichte

The Monte Ceneri transmitter was first established as the nationwide medium-wave radio transmission station for Italian-speaking Switzerland in 1933. Located on Monte Ceneri in Ticino, it broadcast on a frequency of 558 kHz.1933 mastThe original transmission mast – a 120-metre-high free-standing lattice tower insulated from the ground – was constructed in the Monte Ceneri pass (at 46°8'26"N 8°54'56"E). Today this tower is used for DAB and DVB-T broadcasting, for which purposes a 15-metre-high antenna has been added at the top, so that the full height of the mast is now 135 metres.1978 mastIn 1978 a new facility for the Monte Ceneri transmitter was built north of Isone (at 46°8'19"N 8°59'25"E). This uses as its main antenna a 220-metre guyed lattice-steel mast insulated from the ground and, as backup, a T-antenna, which is suspended between two guyed tubular-steel masts. The main mast – which is the only tall guyed mast in Switzerland, as well as being the country's second-tallest tower-type structure – is equipped with an elevator, the machinery of which is installed in a compartment just above the basement insulator.
