Skyware Global 69cm Rx/Tx Ka-Band Antenna

The Skyware Global 69cm Rx/Tx Ka-Band Antenna is a rugged, commercial grade product suitable for the most demanding applications.

  • The pressed steel reflector assures the surface accuracy needed for Ka-band performance. Pre-galvanized steel with a powder coat finish guarantees excellent corrosion resistance and long life.
  • The pressed steel back structure provides for precision alignment of the reflector and support of the RF assembly without distortion.
  • The reflector optics incorporate a long focal length for excellent cross-pol discrimination or “beam squint”.
  • The heavy gauge steel Az/El mount provides a rigid support for the antenna and incorporates precise fine elevation and azimuth adjustment.
  • This Az/El allows the antenna to be installed on any standard 2” (51mm) or 2 3/8” (60.3mm) OD installation mount or mast depending of customer requirements.
