A high directive and a high gain antenna is necessary at the earth station because the losses over the long t n path is very high the signals power reaching back to the earth station from satellite is very small.
There fore at receiving end a parabolic dish antenna with 61m diameter provides a high gain and thus amplify the signal power.
So parabolic reflectors increase the gain of antennas in satellite communication system.
