PURPOSE:To reduce wind pressure applied to a structure partially and to improve reception performance by forming a bent part which is wound around the pole of the structure, a U bolt hole for a 1st cylindrical column fixation, and a band through hole in the same plane of a parabolic antenna mounting metallic fixture, and forming a U bolt for a 2nd cylindrical column fixation in a plane crossing said plane at right angles. CONSTITUTION:A slit hole 6 is formed in the bent part which is one of two orthogonal surfaces of the mounting metallic fixture 1 for an antenna and wound around the longitudinal pole 11 in parallel to the other abutting surface 2. Then the U bolt hole 4 for the 1st cylindrical column fixation, band through hole 7, and a raised part are formed on the same surface. Further, the U bolt hole 5 for the 2nd cylindrical column fixation is formed in the other surface, a cylindrical column 15 is fixed in the bolt hole 4 of the mounting metallic fixture 1 with a U bolt 9, and the parabolic antenna 12 is fitted to the column 15 with an elevation setting metal fixture and an elevation fine adjusting metallic fixture 14. Then the wind pressure applied to part of the structure is reduced and the limitations of its fitting place are eliminated.
