It is often claimed that the Ku-band (12 GHz) is better than the C-band (4 GHz) for TVRO reception because a parabolic antenna of a given diameter has higher gain at the higher frequency. Though the gain is undoubtedly higher, check the difference in path loss at the two frequencies to find out if there is really a net improvement in the signal strength obtained for a given receiving antenna diameter and transmitter EIRP. Are there any other advantages of the Ku-band over the C-band for satellite television broadcasting
