Radio and TV broadcasting in Pretoria is supplied via a network of VHF/FM and UHF transmitters and repeaters owned and operated by Sentech - South Africa's state-owned broadcast signal distributor - from four transmitter sites in and around the city. A number of community radio stations operate transmitters from non-Sentech sites.
The inception of an FM broadcast service in South Africa, began on 1 September 1961 from what is now known as the Sentech Tower in Brixton, Johannesburg. The remainder of South Africa was initially served by medium wave transmitters, which were essentially localised to the larger centres. A massive drive through the 1960s and 70's saw the roll-out of the FM network to the rest of the country. Much of the original equipment supplied was through technology exchange programmes, meaning that the transmitters were of European design, but manufactured in South Africa. Original networks were based on 3 kW tube FM equipment, operating into channel combining equipment to allow the use of a common transmit antenna system, with a gain of around 10-12 dB. Sentech embarked on a huge programme in the late 1980s to effect replacement of these ageing FM transmitter and antenna systems. In world terms, it was the single largest contract awarded to a local manufacturer for the supply of FM transmitters.
In South Africa, digital migration still has to happen. Currently, analogue TV occupies the VHF frequencies where digital radio needs to migrate. Once digital migration is done, South Africa will have Digital Terrestrial Television (DTT) and listen to digital radio on the DAB system. For now, virtually all South Africans rely on analogue terrestrial (FM/AM/SW) broadcasts for their radio consumption.
Gelukskroon is the main broadcast site for Pretoria, situated west of the city close to the Hartebeespoort Dam. It is designed to beam signals down into the valley ("moot") formed by the Magaliesberg. Twelve radio and six TV services are broadcast from this site.

All major transmitting stations in Pretoria are broadcasting DTT Multiplexes 1 and 2 on channel 54 and 58 as part of the Gauteng allotments in DVB-T2. The two trial bouquets include SABC channels, etv, Soweto TV, Tshwane TV, Mindset Health and Education, Lesotho TV and some encrypted DSTV channels.
The following medium wave and short wave radio stations can also be heard in Pretoria. Some stations will be clearer at night. Short wave frequencies vary according to time of day. More information is at www.sentech.co.za.

SHORT WAVE (all at Meyerton, Gauteng)
Due to Pretoria's proximity to Johannesburg, most radio services broadcast from the 234m high Sentech Tower in Brixton, Johannesburg can also be heard in the southern parts of Pretoria (where the line of sight is not blocked by the Magaliesberg or ridges) These include:
In certain areas of Pretoria (especially on hilltops) it is also possible to pick up radio stations transmitted from Sentech's sites at Thabazimbi, Limpopo and Middelburg, Mpumalanga.
Excluding the SA Radio League, there are 36 conventional (FM/AM/SW) radio stations available in Pretoria (including those broadcasting from Johannesburg).
