  • Page 8: Mounting Preparations - Horn Antenna

    This information applies only to special versions! the polarisation plane is marked on the instrument. VEGAPULS 68 is also available in versions where the antenna has a bigger diameter than the process fitting (thread, flange). The antenna must therefore be disconnected from the process fitting before mounting.
