SENTECH’s Broadcasting and Digital Services Reaching New Frontiers


SENTECH is the premier provider of electronic communications network services to the broadcasting and communications industry. SENTECH is licensed to provide Electronic Communications Network Services (ECNS) and Electronic Communications Services (ECS) services.

SENTECH has 17 offices in South Africa to support around 350 terrestrial broadcast sites. SENTECH has infrastructure that provides up linking and down linking of programmes via satellite and can be used for bi-directional communications as well as for DTH (direct to home) broadcasts. Our masts at high-sites are used for the broadcast of television and radio to the public. These facilities are also utilised by other telecommunications services providers such as cellular phone operators, wireless internet service providers, government entities and private telecommunications companies.

SENTECH fulfilled its mandate by concluding its DTT infrastructure installation process of the 178 transmitter stations nationwide and a Direct-To-Home (DTH) broadcasting infrastructure to ensure 100% DTT access for South African citizens.

SENTECH has successfully completed technical trials for both DRM and DAB+ digital radio broadcast systems. The trials were carried out in Pretoria and Johannesburg and proved very successful, particularly the DAB+ trial as many newer cars come fitted with radios able to tune into DAB+ signals.

The Company has expanded its footprint to clients in sub-Saharan Africa to provide broadcasting managed services such as Digital Terrestrial Television (DTT) solutions, Digital Radio (DAB+), training and consultancy services. SENTECH offers a wide range of services designed to meet the needs of broadcast and telecoms operators across the continent.
