Sentech currently provides FM broadcasting services to 17 SABC Public Radio Stations, 20 Commercial Radio Stations and more than 65 Community Radio Stations throughout South Africa, reaching over 10 million listeners. The high quality of signal integrity makes FM (Frequency Modulation) the frequency spectrum most favoured by audio broadcasters.
