• The uplink frequency is the frequency which is used for transmission of signals from earth station transmitter to the satellite.
• At higher frequency attenuation is more hence more power will be required for signal transmission to ensure that it reaches the destination with the required minimum power.
• Higher power requirements involve the use of high power amplifiers with high ratings and heat sinks.
• This will increase the weight and power supply ratings will not make any difference.
• However for the satellite this will result in higher power consumption, which results in avoidable inefficiency.
