Probecom 7.3m earth station antenna
1 Introduction
7.3-meter Earth station antenna,which uses a shaped parabolic reflector .provides high gain and exceptional pattern characteristics as well as low VSWR.its electric performance meets the FCC regulation 25.209,IESS (intelsat).or ITU-RS recommendation 580 sidelobe specification (domestic and international standards).The main reflector surface is comprised of 16 infividual adjustable aluminum panels.The panels of the main reflector are comprised of aluminum sheets and ribs which are stretch-formed,and are riveted on the special mould.The 7.3m antenna sttucture consists of the pedestal,reflector and the feed system,as shown in fig.
