ANTENNA MOUNT

PURPOSE:To attain miniaturization and to simplify the compensation control against shock by tilting the X axis to a plane orthogonal to the Az axis in the three axis structure comprising the Az, X and El axes. CONSTITUTION:The X axis 14 is fitted freely turnably with a tilt angle K deg. to the orthogonal line of the Az axis 13 in the Az frame 13a. An X axis turning angle detector 15 detecting the turning angle of the axis 14 is fitted to the frame 13a. Further, the El axis 16 orthogonal to the axis 14 is fitted to the frame 13a freely turnably and an antenna 17 is fixed to the El axis frame 16a. Prolonged lines of the axes 13, 14 are crossed together at one point of the axis 16. A horizontal base 18 is fitted to the X axis frame 14a and detectors 19, 20 detecting the tilt in the directions in parallel with and orthogonal to the axis 16 are installed to the base 18. Through the constitution above, the driving of the axes 13, 16 has only to be controlled and the tilt detected by the detector 19 has only to be zeroed, it is not required to make operation for all the three axes.
