How to Achieve a Greater Satellite Signal with the Right LNB

A satellite dish system is a sophisticated way of watching television. The signal originates with a satellite above the earth’s atmosphere. That signal must travel a long way to a satellite dish, which has a device that collects the signal bouncing off the dish and sends it to a receiver inside a home. That receiver is connected to a television, on which the user views the signal. This is a simplified explanation. It is necessary to process the signal before transmitting it from the dish to the receiver and the signal goes through some big changes in this process. The device responsible for this is the LNB, which stands for low-noise block downconverter. This is one of the most important parts of a satellite television system as it plays a significant role in determining the quality of the satellite signal. Learning how the correct LNB can help viewers achieve a better satellite signal, as well as learning the basic principles of LNBs, the consumer can choose the right product for his needs. Further, learning how to set it up with the satellite dish and adjust it properly can help the consumer enjoy years of improved signals. Whether purchasing the product on eBay or in a local high street shop, approaching the buying process intelligently is crucial.

How to Choose the Right LNB
One important aspect of achieving an excellent satellite signal is choosing the right LNB to go with a satellite dish. While the signal may only be as good as the dish is capable of delivering, the right LNB helps ensure that no signal quality is lost when processing the signal and sending it to a satellite receiver. This section provides advice on how to choose the right LNB by considering a few key features and being aware of the different types of LNBs.

LNB Types
There are a few types of LNBs to meet different standards around the world, but UK satellite owners usually find that their LNBs are, in fact, Universal LNBs. Also known as Astra LNBs, they have two modes of operation, one in which they process low band reception of 10.70-11.70 GHz and one in which they process a high band reception of 11.70-12.75 GHz. These are the frequencies of the satellite signals, with the processed intermediate signals registering in the range of 950-1950 MHz and 1100-2150 MHz, respectively.

LNBs may also feature numerous coaxial outputs to send signals to various satellite receivers around a house. Those with two outlets are called twin LNBs, those with four, quad LNBs, and those with eight outlets are called octo LNBs. A quattro LNB has four outlets with each outlet responsible for delivering a quarter of the various channels available. Each outlet sends a signal to a multiswitch device, which then distributes the requested signal to each receiver in a building.

How to Position and Tweak an LNB
Choosing the right LNB is only part of the process of maximising satellite signal performance. Another important aspect is positioning and tweaking the LNB. This section describes how to set up an LNB on a satellite dish and how to skew it for the best possible signal transfer.

Setting Up an LNB
An LNB attached to an arm and the feedhorn must be positioned so that it can pick up waves from every part of the satellite dish. It should not align with any area on the satellite dish because it generally picks up noise from whatever object is in its reception area. Conversely, if it does not line up with the whole surface area of the dish, it cannot pick up a signal from whatever area is outside of the alignment area. The precision this alignment requires means it is often best left to professionals to perform.

Conclusion
An LNB is a sophisticated device that processes a weak, extraordinarily high-frequency satellite signal into strong, intermediate-frequency signal a coaxial cable is capable of delivering to a receiver. Because it processes a satellite signal, an LNB is responsible for the quality and strength of that signal and, therefore, how clear the picture appears on the connected television. This guide has explained in depth how LNBs work and how to choose the right one for a satellite television system. It has also provided advice on how to set up an LNB on a satellite dish and how to adjust its rotational angle to ensure the best reception. eBay is a good source to buy an LNB from. The site contains a broad selection of these devices, making it possible to find one that meets just about any buyer’s preferences. Purchasing an LNB can be a challenging process if a buyer does not know what to look for, but following the information in this guide, readers should be able to successfully purchase the right LNB and receive great satellite reception on their televisions
