You need to know two major things right away:
- Design a VSAT transmitting network, first you need to know the information capacity and quality which need to transmit,each communication link from each information, firstly calculate the occupied bandwidth and occupied Satellite transmitting power.
- According to Satellite transmitting power and communication quality specification, through link budget analyze the intermodulation effect between the uplink, downlink and transponder non-linear and calculate VSAT earth station G/T value, and then you can get VSAT antenna diameter.
Therefore, for how to buy VSAT antenna,firstly you should fix the bandwidth, via bandwidth getting occupied Satellite power, adjust VSAT antenna diameter so as to make them meet the necessary Satellite power.Antesky is aprofessional vsat antenna suppliers and vsat antenna manufacturer.
