How exactly are satellite signals transmitted?
Satellite transmissions start with the uplink signal, which are transmitted by very large fixed satellite dishes up to the satellite in orbit above the earth. The satellite then retransmits the signal on a lower frequency down to a general geographic area of the earth with what is called the downlink signal. On the ground, home satellite receiving equipment converts the downlink frequencies to the even lower 950-1450 MHz standard frequency block. The signal then travels to the satellite receiver for modulation to TV channel 3 and is then sent to the television itself.
