Zusammenfassung:	An RF communications transmitter system comprising a processor, a switch and a plurality of feedhorns. The switch is configured to receive a feed signal of a frequency bandwidth. The processor is configured to control the switch to provide the feed signal to each of at least two of the feedhorns for a respective time period. Each of the at least two feedhorns is configured to generate a beam during the respective time period that the feed signal is provided thereto, wherein the beam is formed based on the feed signal and is transmitted to cover a geographic area of the Earth. The formation and transmission of the beams by the feedhorns is controlled by the processor to provide a time-based allocation of bandwidth amongst the beams based on the time period that the feed signal is provided to each of the feedhorns and a respective frequency/polarization reuse scheme.
