C band dishes
Parabolic antennas and satellite television are not something from the past. People still use them. In the 80’s it was mostly the large C band parabolic antennas, generally mesh dishes, from 3 to 5 m. in diameter, for domestic use. They don’t loose the signal when it rains. But now they don’t offer pay service of popular programs any longer. There are still many Free To Air channels, with educational and religious programming; and it is also used as links for professional transmissions.
Ku band dishes
Lately Ku band parabolic dishes have been predominant. They work in a higher frequency range, 12 GHz. The antennas are offset, the LNB is not centered, and they are much smaller. It is easier to install them, but when there is a storm or heavy rain, you can loose the signal.
Initially satellite television was transmitted in analog form. Today most of the channels are transmitted in digital form. It has several advantages: there is a correction system that eliminates small errors when the signal gets weaker, and a compression system that allows the transmission of many channels in one of the satellites transponders.
Many channels are scrambled, and it is necessary to subscribe with the company who transmits them, like Sky in Mexico, or DirecTV or Dish Network in the United States, or Shaw Direct in Canada. But there are also many open channels, which can be seen in C band or Ku band with FTA (Free To Air) receivers.
The Mexican satellites are transmitting many free channels, educational, local stations from different states, and channels from other Latin countries. And in other satellites there are many ethnic channels, with programming from various countries from Europe, Arabic countries, China, Korea, and many more.
