TV Translator
From Biocrawler, the free encyclopedia.
A TV Translator is a device that receives television signals and retransmits/repeats them on another frequency. It is a repeater They are used to extend the range of the original signal into area that can not receive it otherwise.
For example, in Canberra, Australia, the main television transmitter is on Black Mountain in the centre of the city. To the south is the Lanyon Valley. TV signal is not able to be received by those there because of the hills. A translator was installed on top of Tuggeranong Hill so that the signal could be received from Black Mountain and then repeated into the valley.
There are several signals and the translator must be fitted to carry each channel. This is why translators do not always have the same selection of channels as the main transmitter.
The translator must broadcast the channels it receives on a different frequency to avoid interference with the original broadcast.
