Kashima 34m Antenna

34m antenna

34m antenna, constructed in 1988, has the largest aperture in the Kashima Space Research Center. It is capable to receive multiple frequency bands spanning from 1.35GHz to 43GHz. This capability was made possible by a combination of various advanced technologies, such as the accurate surface of main reflector, the steerable sub-reflector system, and the multi receiver trolley system. This antenna is used for various purposes like geodesy (Very Long Baseline Interferometry), astronomy, and radio science.
