Uplink transmitter cable losses.

Uplink antenna aperture efficiency e g. Transmitting antenna with an efficiency of 75 and diameter of 3m. If you are using a high power spectral density uplink such as a feeder link for broadcasting or a vsat outlink destined for small antennas and have the satellite transponder set to low gain then put a figure like 30 db here. As mentioned above c band satellite will have about 500 mhz of bandwidth between upper and lower frequency limits.

Satellite altitude of 30 000km. Uplink antenna power at the feed w. Now as would have thought separate frequency bands are always allocated for uplink and downlink signals often separated by a gap maybe for future allocation since the span of guard bands. Up link path loss depend on up link frequency distance between satellite and ground station.

Up link frequency up link frequency is frequency at which ground station is communicating with satellite. Ku band satellite will have 14 to 14 5 ghz range in the uplink and 11 7 to 12 2 ghz frequency range in the downlink. Uplink antenna diameter m.
