Broadband by Satellite
Did you know we can get a broadband internet signal almost anywhere on earth through the use of satellites? This shouldn't be too much of a surprise—after all, by now most of you have heard of people using mobile satellite phones to place calls from deserts, oceans, and mountaintops. It's not that much of a jump from a radio signal to an internet signal.
Due to the nature of Broadband By Satellite technology , it is not the best choice for someone simply surfing the net at home in a big city with several high-speed broadband internet service providers (ISPs). Broadband by satellite, however, is highly useful for people with no other internet options, living miles and miles from the nearest ISP. This article will describe the advantages and disadvantages of broadband by satellite.
Advantages of Broadband by Satellite
Location
First, the main advantage of broadband by satellite is that you can get a broadband internet signal anywhere on earth, no matter how far you are from the nearest Ethernet port of cable connection. This is useful for people who live in remote rural locations where the only internet option available is the agonizingly slow 56 Kbps dial-up telephone modem connection.
Mobility
Second, by its very nature, broadband by satellite is a wireless connection that allows considerable freedom of movement. This is particularly useful for maintaining an internet signal in mobile locations, such as while in moving vehicle like trains or in a ship at sea.
Disadvantages of Broadband by Satellite
Line of Sight
In order for a satellite dish to receive a broadband internet signal, it must have a free line of sight to the geostationary satellite in orbit. Obstacles such as buildings, trees, and even leaves can get the way of line-of-sight and block the signal, leaving you with no connection.
Weather
Although rain will not block a broadband by satellite signal, it will cause an interference known as "rain fade." Rain fade results in slower upload & download speeds and a patchy connection.
Connection Speed
When an internet signal has to travel 22,000 miles to a satellite in earth's orbit and back, a certain about of latency (the delay between requesting some data and getting a response) is unavoidable. The average latency for Broadband By Satellite is between 500 and 900 milliseconds—much worse than even a dial-up internet connection, where the latency is only 150 to 200 milliseconds. Although this slow data transfer speed is just fine for basic internet usage—email and web browsing—it is too slow for computer applications that require real-time internet access, such as internet gaming, videoconferencing, and VoIP (Voice over IP) telephone conversations.
Cost
Broadband by satellite costs considerably more than earth-based, wired technology like DSL or cable modems. On average, broadband by satellite costs two three times as much as from a land-based internet service provider. Finally, Broadband By Satellite equipment such as the satellite dish and satellite modem costs between $600 and $2000, considerably more than a cable or DSL modem, which usually cost less than $150

What to do when our TV dish says "Searching for satellite signal"?
We are in a process of having the siding installed and they guys were very careful about moving our TV dish and installing it in the exact same spot.
However, now we cannot watch TV. When I turn it on, I get a message, "Searching for satellite signal".
Thanks.
it has to be precise. just putting it back in the same spot doesnt mean anyhing. youll probably have to get the dish company to come out and redjust it. or make life easier and get cable

Satellite Dish $78.07 High Quality Content by WIKIPEDIA articles A dish is a type of parabolic antenna designed to receive microwaves from communications satellites, which transmit data transmissions or broadcasts, such as satellite television. The parabolic shape of a dish reflects the signal to the dishs focal point. Mounted on brackets at the dishs focal point is a device called a feedhorn. This feedhorn is essentially the frontend of a waveguide that gathers the signals at or near the focal point and conducts them to a lownoise block downconverter or LNB. The LNB converts the signals from electromagnetic or radio waves to electrical signals and shifts the signals from the downlinked Cband and/or Kuband to the Lband range. Direct broadcast satellite dishes use an LNBF, which integrates the feedhorn with the LNB. (A new form of omnidirectional satellite antenna, which does not use a directed parabolic dish and can be used on a mobile platform such as a vehicle was announced by the University of Waterloo in 2004.

What Is the Reason of the Low Quality Satellite Signal and How to Solve This Problem?
Some of the fans of satellite TV will find their terminal don't work well even if all the devices on in the satellite terminal are new. If the user meets such a problem, it mainly happens on the signal quality.
1. The problem about the signal is often happens when the satellite antenna is not in a proper position. So choosing a proper place for the satellite antenna is very significant. The direction of the satellite antenna should have nothing block. The antenna should also be away from the microwave station, transposer station or the radar station. These sources of disturbance will affect the satellite signal greatly. If the antenna is on the ground and there are trees or houses, the antenna will be affected. If the antenna is at roof and there is an enclosure around it, or the antenna is just under the microwave receiving tower, or many antennas in the same place; all these situation will do harm to the receiving of satellite signal.
2. The quality of the satellite antenna should reach the standard. The quality of the parabolic dish antenna should reach the standard. This is very significant to the signal quality. If the parabolic dish antenna doesn't have a good quality, the signal will not be able to focus on the feed source.
3. The focal point and the focus of the LNB (Low Noise Block). The focal point and focus are very significant parameters. If you set the focus to the right distance, you will find the strength of the signal improve a lot.
4. The satellite signal splitter. Since the channels of the satellite is increasing, there are always more than one channel in one polarization way. If we want to receive these channels, we have to use the satellite signal splitter. The splitter will reduce the strength of the satellite signal.
5. Special interruption. In an ordinary situation, the satellite terminal will work well if all the device of the terminal is designed according to the right standard and in good working condition. However, some of the nature phenomena will effects the terminal. If the sun transit outage happens, the electrical wave given out by the sun will effects system and the signal will be interrupted. If the satellite, earth and the sun is in one line, the antenna will also not be able to receive the signal send out by this satellite.
