  Applications:

  • Deep parabola for better parameters
  • Easy installation: first the mount, then the antenna with just 2 screws
  • Precise elevation (gradient) and azimuth adjustment of ±20°
  • Extreme wind stability
  The antenna is supplied with a mount that allows for easy mast mounting. The mount can be mounted separately on the mast.
  Then simply hang the antenna with the microwave unit.
  
  The mount allows for precise adjustment in both directions. Suitable for right- and left-hand mounting. In areas where strong winds are expected, mounting on a mast with a minimum diameter of 70 mm is recommended.
