How to Directly Install a Satellite Dish?
A satellite dish is used to pick up and send out electromagnetic signals, usually relayed by communication satellites orbiting around the earth. It can also be used for data, radio, or television. They come in various sizes and designs and also used to receive satellite television.
A satellite captures satellite television signals that reach a viewer’s house. A regular dish is normally consists of a bowl-shaped surface and a central feed horn. A feed horn is used to guide signals between the transceiver and the reflector. It also filters unwanted signals from contiguous channels and other close communication satellites by selecting the property of waves to be received. A transmitting satellite dish sends a signal through horn while the dish focuses the signal into a narrow beam. Conversely, a receiving dish gathers the signal inward and focuses it towards the feed horn and into the controller.
The installation site must be 75 meters or 246 feet on or after the house and must be clear from signal obstructions. Also, think about the local building codes and possible microwave interferences from radio or television towers in the vicinity. Clay soil is a superb ground for installing the base. The base must be primarily installed. The base is a solid foundation that extends below the frost line where a concrete base tube is set. However, a slab increase installation is also considered to be a more stable method than a typical base foundation. It is essential for unstable sites to select the right installation of satellite dishes. The slab must be 1.6 square feet wide by 3.2 feet deep or 0.5 meters wide by 1 meter deep. After digging the soil to a correct depth, the concrete must poured a triangular steel and mount fixture that is embedded into the concrete. The platform is then attached to the triangular steel mount. A satellite dish must be cleaned twice a year. This is done by tightening and lubricating its bolts as well as trimming destructive weeds and trees around it. The arrangement of the dish should also be adjusted to correct bad reception.

The Major Concern in Design and Analysis of Satellite Link
Satellite links are used to deliver long distance telecommunications such as voice or data services, broadband internet services, television broadcast and communications with remote and hard to reach locations. Satellite link consists of an uplink and a downlink. Uplink connects ground station to satellite while downlink connects satellite to the receive ground station. Signal quality in the uplink depends on how powerful the signal is transmitted from the source ground station and how the satellite receives it. On the downlink side, signal quality depends on how powerful the satellite retransmits the signal and how the ground station receives it.
The main purpose of satellite link design is to maximize link data rate while reducing the BER (Bit Error Rate) at the receiver subjects to the constraint of received power and channel bandwidth. The BER of a satellite link is a function of Eb/No, which means energy per bit noise density ratio in the information channel. A satellite communications system designer must ensure a minimum Eb/No in the receiver channels to satisfy the link BER criteria which also meet the constraints on satellite transmit power and RF bandwidth. In digital transmission, Eb/No in a baseband channel relies on C/N (carrier to noise ratio) of the receiver, the type of modulation used in the baseband channel and the channel bandwidth. Hence, the major concern in design and analysis of satellite link is to calculate and evaluate the link C/N in which C is the received carrier power in the earth station/satellite and N is the noise plus interference (caused by earth stations of adjacent satellite) power in the receiver.
Rain is the major destruction of satellite signal. Rain attenuation is a function of rain rate at ground station location and satellite link carrier frequency. Average charge of rain rate (mm/hr) of a country can be obtained from the department of Meteorology of that country. Rain effects become stern at wavelength approach the rain drop size. So you have to ensure that the satellite link can overcome the maximum attenuation induced by the rain. Hence, accurate assessment needs to have evaluating link parameters.

The Comparison of Cable TV and Satellite Internet Service
How do make your mind up which service to go with – satellite TV or cable TV? There is no doubt that both services proffer great services, but there can be enormous differences in cost, and if you’re not careful, you may use up a lot more than you need to for programming you can get for a better price. In this article I am going to compare satellite TV and cable TV and break down which service offers the best deals, and at your convenience.
The world is much more linked than it used to be; because of the far-fetched advancements in technology throughout human civilization we are now able to watch events on the other side of the world as they take place in real time. We also can now verbally and visually correspond with someone in another country as well as someone in outer space. Every field of business continually adjusts to the newest technologies in order to stay competitive. This is very true in the field of providing Television programming service. The competition is basically between Cable TV providers and Satellite TV providers, such as Dish Network. Because of their ability to make use of modern technology in so many different kinds of situations, Dish Network is starting to leave its Cable competitors behind.
One of the many great benefits of having Satellite Television through Dish Network is that you are not limited to sitting in your house in order to look at your favorite shows. Because you are receiving the programming signal through a small dish and not a ground cable, you can be almost everywhere and still watch television. People are attaching dishes to their RVs, rolling down the open road, and still catching the news or their favorite sports team in action. Others are putting dishes on their boats and keeping track of weather forecasts while on the open water. Clearly, this is something Cable Television technology cannot even begin to propose.
If you have Satellite Internet service, you can also power this and send emails about your situation to your friends and family. The ability to communicate, and get information is vital in situations like these.

The Advantages of Satellite Images
Satellite images can make forecasting weather conditions much more clear-cut because they show accurately what is happening in any given location. These images show the concentration, speed and direction of the storms, allowing a weather forecaster to give more precise information to the areas in front of the storm. By merely observing a satellite image, the forecaster can see what changes are taking place within a certain storm system over a period of time. In case the storm is escalating or breaking apart, changing its directions, speeding up or slowing down, this will all become noticeable in satellite images. This becomes particularly useful in areas prone to hurricanes or tornados. These images permit forecasters to foresee with relative accurateness what areas may have the greatest risk of being hit by an approaching storm, and allowing the local people to get ready.
These images can also help forecasters to find out the sternness of the upcoming storm. They can predict heavy showers or snow storms, or even light rain or flurries according to what the satellite images illustrate. They can also perceive where rigorous conditions may be forming with in a larger less harsh system. It is very vital to have these satellite images as these give information, and let other people have time to prepare for the upcoming storm, and help photographers find out where to set up to get some of those far-fetched storms or lightning pictures you’ve seen. By observing the spot of severe weather cells within storms, photographers are able to settle on if they will have a good chance to capture or take a picture of tornado, cloud structure or lightning pictures. They can also foretell when and where the safest places or positions for taking these pictures will most likely be.
Satellite images have made weather forecasting much more truthful and functional than it was not so many years ago because of the details and quantity of information obtainable. Forecasters are now able to give the public a much better image of what to anticipate in the next week, day or hour because of information provided by these satellite images.
