Cape Town TV is a community television channel that broadcasts in Cape Town, South Africa. It launched in September 2008 with a one-year, "temporary" license and thereafter won another such license in September 2009. It is a non-profit organisation that is licensed as a community broadcaster in terms of South Africa's Electronic Communications Act. == Signal Transmission and Reception == CTV is a free-to-air channel that broadcasts on an analogue transmission. The channel transmits from a single low-power transmitter located on Tygerberg hill, to the north of Cape Town. This site provides the widest possible coverage of the Cape Town metropolitan region, although it is only licensed (by ICASA) for low-power transmission. The channel is broadcast on the frequency 607.25 MHz (channel 38) on the UHF band.〔Television Frequencies〕 Viewers can pick up the channel if they are in line-of-sight of Tygerberg mountain and their television aerials are oriented towards this site. Automatic or manual tuning of the television set should pick up the channel between the signals of SABC3 and eTV (). The signal will vary in strength depending on how far distant the viewer is from the Tygerberg site. In order for the channel to gain a stronger signal and increased coverage of the region, additional transmitters will be needed, some of which will be of a considerably higher power. However, each transmitter is licensed to transmit particular frequencies and there is at present a shortage of available frequency spectrum (in South Africa generally, but particularly in Cape Town). Not only will CTV require considerably more funding to acquire such transmitters, but ICASA will also have to license additional frequencies for the channel. This is unlikely to happen before frequency spectrum is 'freed up' by the migration from analogue to digital television transmission, which is scheduled to be completed in 2012.〔Re-visioning Television: Research on the policy, strategy and models for the sustainable development of community television in South Africa.
