About
The Double-mirror Ka-band Parabolic Antenna forms the required servicing area, radiates signals within the 20 GHz operating frequency band, and shapes required polarization. A Cassegrain-type mirror antenna, it features a 1800 mm aperture main reflector and 140 mm hyperbolical subdish. The reflecting surface profile rms deviation is ≤0.3 mm accounting for utilization factors. Reflector material is CFRP polymeric composite. Antenna mass is 10.5 kg. Flight-qualified.
