Unicable is an advanced feature in set-top boxes and satellite receivers that allows reception of multiple satellite channels from a single cable or satellite pair. This feature greatly simplifies the installation of a satellite system by allowing multiple devices to share a single cable connection, eliminating the need to lay many cables for each channel or satellite tuner. Unicable operates on a "one cable fits all" principle, meaning that all satellite receivers connected to a single Unicable system can use the same cable to receive different channels.
