Basically a FTA system used for receiving a parabolic antenna, a LNB coaxial cable and a receiver sep top box, better known in the jargon as deco, these items are still not very easy to get, but several countries are now pointing to this technology for telecommunications since there are not many problems with the distancesfor example a House away from the city would not have complications to take the signal emitted by the satellite, there are satellites transmitting at this time for almost all America South and with a system of these serious almost the same take it from Argentina to Venezuela. The FTA system installation, is not very complicated and is not necessary to have much knowledge in telecommunications, simply point the antenna to the desired satellite by moving it to pick up the signal. Satellites transmitting FTA are many and are scattered to orbiting in the belt of Clarke, named after who discovered it, in this belt are satellites are kept quiet in a single position, for this reason it is not necessary to move the antenna again and you see behind the satellite, these satellites are those called geostationary. The number of channels that can be viewed with a free satellite TV system is very wide, but depends on several things. The number of antennas connected to deco the size of the number of channels antenna having each targeted satellite is true that there are people who come to have thousands of channels, because many antennas connected to your deco and of different sizes, but this would make a good investment of money. Also if we seek us much on this subject we find the true meaning of the FTA has subverted, as nowadays many people may become your decos decode large number of payment channels.
But if it is illegal and unethical. Finally is important say today is this much talk in the world of the new digital television terrestrial (DTT) which I do not well, seems to me that it should promote more FTA, by with single DTT would signal those who are a few kilometres from digital tv transmitter. In contrast with FTA, as I said before is possible to cover large areas of the Earth with a single satellite, if set free most of the channels in one of these satellites could see a large number of channels provided that we are within reach of the footprint of the satellite.
