  • 1.11.3M C / L dual-band antenna function requirements
  • 1) Antenna diameter: 11.3M
  • 2) Antenna type: improved Cassegrain antenna for primary and secondary reflectors
  • 3) Antenna base: Kingpost base, azimuth and height lead screw drive
  • 4) Antenna travel range: El: 0~90°Az: ±80° (three segments)
  • 5) Polarization mode:
    C band: double round Bohr.
    L-band: double round Bohr.
  • 6) Wind load:Maintaining accurate wind speed: stable wind speed 13m / s, gust 20m / s
    Running speed with reduced speed accuracy: stable wind speed 20m / s, gust 27m / s
    Collect the antenna’s wind speed: 35m / s (drive the antenna to the sky)
    Save wind speed: ≤55m / s (the sky lock position antenna is not destroyed)
  • 7) Three proofing functions:
    The antenna has the ability to resist moisture, mildew and corrosion; there is no obvious corrosion of the antenna life. For steel parts, hot-dip galvanizing or hot-dip galvanizing or sand blasting, then rust-proof primer, and finally white paint. For aluminum parts, anodizing, zinc zinc silicate primer, and white coating on the surface.
