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 3kW tube FM equipment, operating into channel combining equipment to allow the use of a common transmit antenna system, with a gain of around 10-12dB. 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.
Pretoria-Gelukskroon Transmitting Station
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 FM broadcast band is a range of radio frequencies used for FM broadcasting by radio stations. The range of frequencies used differs between different parts of the world. In Europe and Africa and in Australia and New Zealand, it spans from 87.5 to 108 megahertz (MHz) - also known as VHF Band II - while in the Americas it ranges from 88 to 108 MHz. The FM broadcast band in Japan uses 76 to 95 MHz, and in Brazil, 76 to 108 MHz. The International Radio and Television Organisation (OIRT) band in Eastern Europe is from 65.9 to 74.0 MHz, although these countries now primarily use the 87.5 to 108 MHz band, as in the case of Russia. Some other countries have already discontinued the OIRT band and have changed to the 87.5 to 108 MHz band.

FM broadcasting is the method of radio broadcasting that uses frequency modulation (FM). Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to transmit high-fidelity sound over broadcast radio. FM broadcasting offers higher fidelity—more accurate reproduction of the original program sound—than other broadcasting techniques, such as AM broadcasting. It is also less susceptible to common forms of interference, having less static and popping sounds than are often heard on AM. Therefore, FM is used for most broadcasts of music and general audio. FM radio stations use the very high frequency range of radio frequencies.

A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater or complementary station (Mexico), is a broadcast transmitter which repeats the signal of a radio or television station to an area not covered by the originating station. It expands the broadcast range of a television or radio station beyond the primary signal's original coverage or improves service in the original coverage area. The stations may be used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band.
