So you want to know more about Sentech Television Tower in Johannesburg?📻📺 The tower was previously known as the Albert Hertzog Tower (named after the late apartheid minister of posts and telegraphs). It became better well-known as the Brixton Tower. It was built to host TV and radio transmissions. It hosted FM radio transmissions up until 1970. It was one of the first towers in the world to combine 6 FM channels simultaneously into 1 common antenna. In 2001, the name changed from Albert Hertzog Tower to Sentech Tower because naming rights were sold to Sentech. Sentech was one of South Africa’s first wireless service providers. Excavations for the land that the tower was built on started in February 1961. They managed to finish building the tower to its full height of 237m in December of that same year. The steel mast at the very top of the tower only took 3 weeks to complete. The tower is made of concrete and 300 tonnes of reinforced high-tensile, mild steel bars. The tower was designed to withstand winds of up to 200km/h. Backup power to the tower is 1MW using two 500 kVa Volvo Generators. 📡 Height: 237m 📡 Constructed in: 1961 📡 Cost to build: R300 000 📡 Designed by: Ove, Arup and Partners 📡 Construction by: Christiani and Nielsen SA 📡 Heigth of steel mast at top of tower: 16.1m 📡 Concrete used for the foundation: 1340 tonnes 📡 Concrete used to build the tower: 5684 tonnes 📡 Location: Symons Road & Putney Road, Brixton, #Johannesburg, #SouthAfrica 📡 Dimensions of the tower’s foundation: 2m deep, 6m wide, external diameter at the base of 25m Up until 1982, there were viewing decks that were open to the public for viewings.
