Broadcast Television stations are heavily reliant on communication with other television production organizations and content delivery companies.
Although land based communications are becoming ever faster, the television industry has been built on satellite communication systems due to the very mobile nature of news and event gathering production units. Live news feeds can be obtained from almost anywhere in the world with a satellite transmission. The signal can be transported around the world an back to base stations with ease.
TV stations use several satellites for incoming and outgoing signals, hence the array of dishes, all of which can be active at any time.
Unlike domestic satellite dishes, commercial dishes need to be capable of receiving low power transmissions from satellites that are not always in ideal locations. The large size of the dishes allows higher signal levels to be captured, from satellites that many be low in the sky and also overcome the problem of weather related dropout occasionally experienced by residential dishes.

These satellites receive the signals from thebroadcast stations located on Earth and rebroadcast them to the Earth The Overall System Early satellite TV viewers were explorers of sorts. They used their expensive dishes to discover unique programming that wasn't necessarily intended for mass audiences. The dish and receiving equipment gave viewers the tools to pick up foreign stations, live feeds between different broadcast stations, NASA activities and a lot of other stuff transmitted using satellites. Some satellite owners still seek out this sort of programming on their own, but today, most Direct to home TV customers get their programming through a direct broadcast satellite (DBS) provider, such as DirecTV or the Dish Network. The provider selects programs and broadcasts them to subscribers as a set package. Basically, the provider's goal is to bring dozens or even hundreds of channels to your television in a form that approximates the competition, cable TV. Unlike earlier programming, the provider's broadcast is completely digital, which means it has much better picture and sound quality. Early satellite television was broadcast in C-band radio -- radio in the 3.4-gigahertz (GHz) to 7-GHz frequency range. Digital broadcast satellite transmits programming in the Ku frequency range (12 GHz to 14 GHz ).
