What exactly are satellites and aerials llandudno? How do they work? What are they used for? Why do we need them? In this article, we’ll give you the lowdown on the history and current use of satellite technology around the world, why it was developed, and how it works.
How does satellite TV work?
A question that many of us have asked at one time or another is how does satellite TV work? Most consumers only think about their equipment, but there is much more to it than that. All our modern conveniences – like cable, Internet and telephone – rely on satellites in one way or another. While most of us are familiar with traditional satellite television, there’s a lot more to it than you may realize. So how does satellite TV work? The answer is surprisingly complex; let’s break it down
Why do we need aerials?
In its simplest form, a satellite dish is just an aerial—basically a very large radio antenna. If you have cable television at home, you probably already know that your provider uses one or more satellites to provide channels via cable—the signal travels from space to your dish and then into your home. If you’re subscribed to a satellite television service, in addition to having access to traditional broadcast networks like NBC and CBS, you can also get speciality channels that cater to different interests like sports or movie buffs.
How many channels do I get?
The number of channels you get is determined by how much bandwidth your dish and receiver can handle. When you order service, a representative will discuss your needs with you to determine what package works best for your home. Channels are sent through a transponder, which is a small box that contains decoders for each channel so your receiver knows where to find them. Each transponder has two different types of bandwidth—one for HDTV, and one for standard definition (SD) programming. The more HDTV channels you subscribe to, the fewer SD channels will be available; conversely, if you subscribe to fewer HDTV channels, more SD programming may be available in each transponder slot.
