7.3 M C Band 4 PortS Antenna —In the Gabon
Genera Background
Probecom 7.3 Meter 4-Port antenna adopts all aluminum re-enforced reflectors, consisting of precisely formed panels with matched radials and hub assemblies ensure the ease of installation. The standard designed azimuth over elevation pedestal provides a cost-effective solution for high stiffness and stability, full orbital arc coverage and fine drive performance, and ensures the pointing accuracy for C-Band Tx/Rx operations.
7.3-meter 4-Port 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 individual 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 structure consists of the pedestal, reflector, sub reflector and the feed system, as shown in Fig.
