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.
TVRO (Television Receive-Only) refers to satellite dishes used for receiving satellite television signals. These dishes are typically larger than DBS (Direct Broadcast Satellite) dishes and are commonly used for receiving programming from satellites located in geostationary orbit. TVRO systems were popular before the advent of smaller DBS dishes.
Satellite dishes that beam radio waves to satellites above the Earth are typically referred to as ground stations or satellite uplink dishes. These dishes are designed to transmit signals to satellites in geostationary or low Earth orbits, enabling communication for television broadcasting, internet services, and other data transmission. They usually have a parabolic shape to focus the radio waves into a narrow beam directed towards the satellite.
They are a valuable commodity, as they have a number of different uses. They can be used to broadcast wireless networks over a large area. They can also be used to receive Free-to-Air satellite TV when properly retrofitted.
Communication satellite dishes are typically located in various settings, including ground stations, television broadcasting facilities, and telecommunication companies' infrastructure. They can also be found at individual homes for satellite television or internet services. These dishes are strategically positioned to establish a line of sight with orbiting satellites, ensuring optimal signal reception and transmission. Additionally, they may be placed on rooftops, in open fields, or on specialized towers to minimize obstructions.
People have satellite dishes to receive television signals from satellites orbiting the Earth. These signals provide access to a wide range of TV channels and programs. Satellite dishes are often used in areas where traditional cable or internet-based TV services are not readily available.
A TV satellite emits signals in the form of radio waves, which carry television programming and other data to Earth. These signals are typically transmitted in specific frequency bands, such as Ku-band or C-band, allowing them to be received by satellite dishes on the ground. The satellite also often emits signals to communicate with ground stations for monitoring and control purposes.
Direct to home (DTH) television is a wireless system for delivering television programs directly to the viewer's house. In DTH television, the broadcast signals are transmitted from satellites orbiting the Earth to the viewer's house. Each satellite is located approximately 35,700 km above the Earth in geosynchronous orbit. 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 ).

Satellite dishes for television began to gain popularity in the late 1970s and early 1980s. The launch of the first commercial communications satellites, such as the Hughes Communications satellite in 1975, paved the way for direct-to-home (DTH) satellite services. By the mid-1980s, advancements in technology made satellite dishes more accessible to consumers, leading to widespread adoption for television viewing.
Satellites receive television signals from broadcasting stations on Earth, which are transmitted to the satellite in the form of microwave signals. The satellite then amplifies and retransmits these signals back to a designated area on Earth using a specific frequency band. Viewers use satellite dishes that capture these signals and send them to a satellite receiver, which decodes the information for display on televisions. This process allows for the distribution of television programming over large distances, including remote areas.
No, satellite dishes are not obsolete and are still pretty popular with some people. the biggest problem with this type of TV service is the fees, credit checks, and installation costs that make it unpopular.
Yes, satellite TV providers provide all the hardware when one subscribes to their service. The hardware usually includes a satellite dish, a receiver box with a personal video recorder, a remote and the satellite TV service.
