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 mountain, to the north of Cape Town. This site provides the wides 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.
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.

Famous quotes containing the words signal and/or reception:
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.”
—Selma H. Fraiberg (20th century)
“He’s leaving Germany by special request of the Nazi government. First he sends a dispatch about Danzig and how 10,000 German tourists are pouring into the city every day with butterfly nets in their hands and submachine guns in their knapsacks. They warn him right then. What does he do next? Goes to a reception at von Ribbentropf’s and keeps yelling for gefilte fish!”
—Billy Wilder (b. 1906)
