Free To Air Satellite

How does free to air satellite TV technically work? Transmitters–usually large dishes up to 40 plus feet in diameter–initially send signals into outer space to satellites orbiting in geosynchronous paths around the earth. Most satellites have at least a dozen so-called transponders, which accept the uplink signal and then return it to earth in a process known as downlinking.

The electromagnetic radiation/radio signals are broadcast at an altered frequency, so that they don’t negatively interact with the uplink signals to the satellite. These free to air signals eventually collect in parabolic dishes–such as the 80 centimeter KU band offset dish produced by Fortec Star. The parabolic configuration concentrates the electromagnetic radiation and converts the downlink via something known as LNBF into signals that satellite TV receivers can read.
