QFH-5180R C-Band Satellite Antenna

The C-Band Antenna QFH-5180R has been designed for use on board of small satellites. The iso-flux pattern has been optimized particularly for low earth orbit (LEO) missions.

The antenna operates in the C-Band (5,150 MHz to 5,216 MHz), which is allocated on a primary basis to Space-to-Earth feeder-links of non-geostationary satellite systems for mobile-satellite services.

The antenna design is compact, solid and very rugged.
