Cable TV delivers high-frequency signals with the audio and visual information to your TV through the standard cable, held in the apartment.

Analog TV supplies a signal via a standard antenna with a rather small capacity.

Cable television signals are more stable than the signals for terrestrial and satellite broadcasting. Cable protects the signal from various distortion and interference, while allowing subscribers to connect a large number of TV channels. Its major drawback is the inability to connect to modern TV models, which were originally "adapted" to digital TV.
