The CATV network is the system through which the users receive television and/or radio signal by using radio-frequency signals.
The CATV network can be built with fibre optics and/or coaxial cables.
This distribution method appeared as an immediate necessity due to the fact that there were signal reflexions that led to disruptions of signal reception in order to avoid an unpleasant landscape with multiple antennae on the buildings and for operation safety reasons.
