How to Install Your Satellite Receiver

Satellite television offers an array of channels that cannot be received with terrestrial equipment. As satellites orbit the earth, they are able to send signals across great distances because they are not limited by the earth's curvature, which hampers terrestrial television signals. So, broadcasts from other countries can be enjoyed easily, and many expatriates use this to keep in touch with television from home. Encrypted satellite signals are first received by the satellite dish installed on the rooftop, but this is not the only device required to view satellite television. A satellite receiver decodes and processes the signals and ultimately delivers the images to the television screen. In order to install a satellite receiver it is first useful to understand how satellite signals work and the features of satellite receivers. Once the buyer has the equipment required, installing a satellite receiver is easy. Satellite receivers are available from high street electronics shops and online, at sites such as eBay.

How do Satellite Signals Work?

Satellites revolve around the earth once every twenty four hours, while the planet completes one rotation. Satellites are always able to deliver signals to a particular location and, because of their position, the signal covers a large area. Satellites also transmit signals between each other. Content providers who produce satellite television channels send their signals to uplink centres where they are encrypted and digitised in order to provide security and quality. The uplink centres transmit signals to the satellites.

When signals are directed to the ground from satellites, they are received with satellite dishes mounted on rooftops. In the middle of the dish is the LNB, a low noise block downconverter. This part of the dish catches the satellite signal. The LNB can be either single, dual, quad, octo, or universal and they differ by the number of outputs that they have. An encrypted and compressed signal is transmitted through the LNB and is processed in the satellite receiver before being sent to the television screen.

Features of Satellite Receivers

Satellite receivers receive encrypted signals from a satellite dish and process them before transmitting them to a television. Satellite television signals are multi channel media, so satellite receivers are equipped with software and signal processors that can switch between channels. Satellite receivers can have several different features which influence the cost of the device. More advanced satellite receivers are similar to computers because they have advanced microprocessors and memory storage circuits. These receivers perform all of the actions required for tuning the receiver automatically, so they are simple to use.

Performance of Satellite Receivers

Performance is an important factor to consider when buying a satellite receiver because the strength of incoming signals needs to be maximised in order to receive the best quality of picture. Performance is largely influenced by the size of the satellite dish. If possible, the receiver should be tested with a satellite dish in order to evaluate how it operates. Satellite receivers with the optional auto peak feature fine tune the performance and can upgrade the picture quality of the received signal. This becomes useful when the signal is affected, for example, on a very windy day. With the auto tune feature, the receiver automatically repositions the dish.

Encryption of Satellite Receivers

Satellite television channels are usually provided to subscribers who pay for them. Therefore, the signals are encrypted for security reasons and the receiver has to decode them. The decoding is performed by a chip inside the receiver. This chip is unique to each satellite television provider. This ensures that people who do not pay for the service cannot decode the signals, even though they may have the necessary equipment.

Compression of Satellite Receivers

Satellite television signals are known for their high quality, but this also means that they require lots of capacity. So, the video and audio data is compressed and this makes the transmission process efficient. The receiver decompresses the files and converts them into an acceptable format. However, digital televisions do not need the conversion process.

Tuning of Satellite Receivers

Television signals are essentially radio waves that are modulated to carry information. This means that their frequency or amplitude is altered during the transmission process. Satellite television signals are modulated with the Digital Video Broadcasting Satellite standard (DVB-S). Satellite providers send more than one channel in a single transmission, so the receiver has to extract the individual channels from the signal. This process is called tuning.

Some satellite receivers are called twin tuners and have an integrated hard drive. These receivers feature two tuners that allow the viewer to watch one satellite channel while recording another. Twin tuners require two feeds that are connected to two LNB connectors. However, single feeds can also be converted into two feeds

Noise Reduction Filters for Satellite Receivers

Noise reduction filters are found on many satellite receivers. They amplify weaker satellite television signals that are coming from some channels. These filters usually remove any flaws from the picture.

Parental Control for Satellite Receivers

Parental control helps to lock certain channels from children so that they cannot view violent or adult channels. These channels can be accessed when a password is entered by a parent or carer.

Installing a Satellite Receiver

Installing a satellite receiver is a simple task once the satellite dish is already mounted and angled correctly. The installation requires only the connecting of a few cables to make the satellite receiver ready.

Connect the Satellite Receiver

Once the satellite dish is in place and satellite television signals are available from the wall socket, the satellite receiver can be plugged in. The exact process of connecting and tuning a satellite receiver varies by brand and model. So, once connected the satellite receiver should be tuned according to the instructions in the manual. Often, tuning occurs automatically, but this depends on the satellite card that is inserted into the receiver.

Install Two Satellite Receivers for One Dish

On some occasions, the buyer may want to install two satellite receivers for one dish. This may be necessary for larger homes where receivers are used in several rooms or where one television is connected to two receivers that work for different providers. This allows the viewer to access a large number of channels. The satellite receiver controls the LNB and two boxes cannot do this simultaneously, so there are various ways to make the system operate. For multiple receivers, multiple feeds can work. This means that the LNB should have more than one feed. Switch boxes can also help to connect two receivers at once. Some satellite receivers have loopthrough sockets that allow the buyer to connect the receivers to each other, while one is connected to the satellite dish. However, the loopthrough feature is limited because only one receiver can control the LNB.

How to Buy a Satellite Receiver on eBay

To buy a satellite receiver on eBay start the search by typing the keywords or phrases into the box that you can find at the top of every eBay page. The most basic keywords for satellite receivers are "satellite receiver", but you can also add the brand of the receiver or the hard drive capacity if you have particular features in mind, such as "Humax 500 GB satellite receiver". You could select customisable options, such as price range, or the item condition after you receive the initial search results. Then you can sort the results by price in order to narrow down the listings. Once you browse through the item listings, you can get further information about that satellite receiver's specification, delivery times, postage and packaging, and the seller's returns policy.

If you have any questions after reading the listing, feel free to address them to the seller directly using the "Ask a question" link. Usually, good sellers, especially Top-rated sellers, are more than happy to provide you with answers quickly. In order to find a good seller, read the feedback and browse the seller's ratings to see what other customers thought of their products and customer service.


Satellite television offers many opportunities to view an array of channels broadcast from around the world. Satellite signals are transmitted to the television screen from satellites that orbit the earth. The encrypted signals are first received by satellite dishes on rooftops and then passed on to the satellite receivers inside the home. Satellite receivers decode the television signals, so that they can be displayed on the screen. As a result, viewers can watch high quality satellite television. Satellite receivers can have several features, such as noise reduction filters and parental control, or the more advanced auto peak function.

Once all of the other equipment is installed, such as the satellite dish, it is easy to install the satellite receiver as it just needs to be plugged in and many models tune themselves automatically. The installation is more complex when two satellite receivers need to be attached to one dish. This can be done by the use of switch boxes, multiple feeds, or loop throughs. eBay sellers offer a selection of satellite receivers that are easy to install.
