The arrival of Satellite TV was characterized by expensive metallic home dishes, usually taking a huge amount of yard space, which installation was very difficult, not to mention all other hassles involved to make them work and the limited dishnetwork providers.

Dish network today is totally different with the current compact satellite dishes in almost every household all over the United States, and established the Satellite TV providers offering a lure of events and news from around the world along with the traditional programming of movies, music, sports, etc.

The concept of dish network is commonly used in reference to Satellite TV, which is closely similar to broadcast television, but a wireless delivering system transmitting the programming via a radio signal through a satellite station, known as dishnetwork.

Satellite TV stations transmits satellite radio signals like broadcast stations do but with a few differences. The traditional powerful antenna transmitting radio waves to the surrounding area when it comes to broadcast television, is substituted by satellite equipment that does not require shooting out from an antenna in a straight line, thus obstacles will not distort or reflect the radio waves.

A dishnetwork receives the broadcast signals from satellites orbiting the Earth, high in the sky, making it possible to reach a large number of customers in the line of site with practically no obstacles in the middle, and just requiring the specialized antenna called a satellite dish.

Satellite TV components include the programming sources, which are those channels providing the programming for broadcast. The broadcast center or central hub of the system, provides the signals from programming sources, beams the broadcast signals to satellites in geostationary orbit of the dishnetwork.

Satellites receive signals from the broadcast station and then rebroadcast them to the ground, where dish network antennas pick up those signals from the satellite passing it on to the receiver in the household, usually a home dish that processes the signal and passes it on to a standard television.

Satellite TV consisted of a dishnetwork which received the transmitted signals but there were not enough programming sources or dish network providers so the antennas usually picked up a few foreign stations but more often NASA activities, live feeds between broadcast stations, or other not related transmissions made through satellites.

Today, Satellite TV customers can get the programming they want through a direct broadcast satellite provider, such as Dish Network and DirecTV. These services transmit digitally in the Ku frequency range (12 GHz to 14 GHz), while early Satellite TV was broadcast in C-band radio in the 3.4-gigahertz (GHz) to 7-GHz frequency range.
