The Sentech Tower, previously named the Albert Hertzog Tower and commonly known as the Brixton Tower, is a 237-metre-high (778 ft) concrete television tower in the Brixton suburb of Johannesburg, South Africa, near the top of the Brixton Ridge. It is a well-known and easily identifiable landmark in the city, alongside its "architectural cousin", the Hillbrow Tower. Although always intended for both radio and television transmission, it carried only FM radio transmissions until the 1970s.
