SHF Directional Antenna System
Key Facts 1 GHz to 18 GHz/0.85 GHz to 26.5 GHz Extremely broadband directional antenna for radiomonitoring, steerable in azimuth and elevation The R&S®AC090 is a stationary directional antenna that can be adjusted in azimuth and elevation. The reflector has a diameter of 0.9 m and – depending on the feed used – receives signals in the range 1 GHz to 18 GHz or 0.85 GHz to 26.5 GHz. The frequency range can be extended to up to 40 GHz by flange-connected options. The R&S®AC090 is used for radiomonitoring tasks, for instance. The following antenna feeds are available
