The most popular type of satellite TV antenna is the parabolic reflector, but it is no the only type of satellite antenna. There are several other kinds that can be used to transmit to and receive from satellites. Which one should you use? It all depends on your requirements and application. The parabolic reflector Perhaps the most widely used satellite TV antenna is the parabolic reflector, also known as the satellite dish. Why? Because the parabolic antenna is considered a ?high gain directional? type. The distance between the satellite and the antenna is very large, so special designs like this ? which can significantly decrease path losses ? are most effective. Parabolic satellite TV antenna also have low noise block converters (or LNB), which is installed right at the feed point. How does it work? The satellite sends out signals with frequencies at 12.2 to 12.7 GHz ? signals that are very rapidly attenuated by coaxial feeders that were used. Feeder length runs several meters (or even more) in installations, so this means that that the signals reaching the television are very weak. LNB solves this problem by (a) amplifying the signal and then (b) converting it to 950 MHz frequency (up to about 1450MHz) ? this is the frequency where the loss caused by the coaxial feeder is significantly less. The LNB's amplification also decreases the criticality of the loss because of the cable to be less critical. The parabolic satellite TV antenna therefore enables use of the domestic coaxial cable as it maintains enough ?high? signal intensity at the receiver.
Although there is fundamentally no difference between the antennas on satellites and those on the ground there are a number of different requirements that need to be taken into account. In the first instance the environmental conditions are very different. As conditions in space are particularly harsh the antennas need to be built to withstand this. Temperatures vary considerably between light and dark and this will cause expansion and contraction. The materials that are sued in the conduction need to be carefully chosen. Satellite TV antenna: What's the best size? Most satellite TV antenna provided by satellite TV service providers are about 18 inches (that's the smallest) to about 31 inches (that's the biggest) in diameter. These sizes are designed for home use, so expect industrial satellite TV antenna to be much bigger. Very small satellite TV antennas can cause some problems. If your satellite TV antenna is too small, its performance may be weakened when it rains outside. Small satellite TV antennas are also prone to interference from other neighbouring satellites.
With the dish,the programs can support over 250 channels of programming. All channels are digital quality and offer HD (high definition) television services that are compatible to your program service.
Satellite television fees for Dish Network start at $31.99/month, while DirecTV charges $41.99/month. Both service providers offer free equipment and free installation in up to four rooms.
Cable television fees average $39.99/month for 64 channels, plus $10.95/month to add digital channels. Installation in one room is $39.95, plus $9.95 for each additional room.
DirecTV and Dish Network offers the biggest variety of shows, movies, sports, and news for the least amount of money. You can watch all your shows in digital video and sound with the option of watching them in HD format and recording them on a DVR (digital video recording) receiver.
Cable television outages average 3% to 5% per year while satellite television outages average about 1%. J.D. Power and Associates ranked Dish Network and DirecTV -- higher in customer satisfaction than any of the cable television companies for the last five years.
With cable's monopoly on programming removed, several companies - the Direct TV division of GM Hughes Electronics, RCA, and the United States Satellite Broadcasting division of Hubbard Broadcasting - have entered the marketplace, providing consumers with more channels for slightly less in monthly fees than cable.
Satellite television has always been considered the highest quality reception that there is. The fact is that the satellite television will get a better reception than cable television because nothing comes between the source and the viewer that can interfere with the signal.
Another important benefit is that, in addition to television channels, the consumer can opt to receive 20 channels of digital audio.
Our recommendation is that both DirecTV and DISH Network offer a much more superior television viewing experience than cable television.
Both are a whole lot cheaper than cable and offer superior picture quality and free equipment and installation. Both also offer outstanding customer service compared to local cable providers.
If you're a sports fanatic and you just have to have that certain premium sports package, then I would recommend DirecTV for all of your gaming pleasures. But if you're not big on sports and cost is an issue, then you might want to go with DISH Network.
Also, remember that DirecTV will require a one year commitment, whereas with the DISH Network there is no contract to sign, meaning you can cancel your service at anytime and not have to pay a penalty.
Whichever service providers you choose, you can't go wrong. I highly recommend that you drop cable and switch to satellite television service today. The vastly superior picture quality alone makes it worth the change. It's like heaven watching television.
