PURPOSE:To decrease volume of packing and to make transportation cost inexpensive by providing a circular arc frame to the front face of a mirror face and providing other frame at the back of the mirror face so as to make plural panels close together thereby stacking them. CONSTITUTION:The frame 6 is provided to the front face of the mirror surface 1 and frames 2-4 are provided at the rear face of the mirror face 1, then the reflection mirror panels are put closely together and stacked to decrease the volume of packing. A parabolic antenna is formed by combining the reflection mirror panels. Thus, the packing volume is decreased and the transportation cost is made inexpensive. |
