The satellite broadcasting antenna is fixed by being sandwiched between the vertical lattices (bars) 33 of. The parabola 30 is installed on the mast 2 via a mast attachment, and is fixed by adjusting the elevation angle adjusting bolt 35 of the metal fitting 31. The specific installation method is to adjust the position of the bolts to the left and right so that at least two lattices (bars) 33 are sandwiched between the plates 3 facing the bracket 1 at the bottom of the lattices (bars) 33, and the nuts are adjusted. Temporarily stop with. After this temporary fixing, the bracket 1 and the facing plate 3 are moved to the upper part of the lattice (bar) 33, and the nut is held by a spanner (not shown) or the like, and the bolt is tightened by a driver (not shown).

A detailed description will be given. As shown in the enlarged view of the main part of FIG. 4 (a), (b), or (c), the bracket 1 provided at the lower end of the mast 2 has laterally long through holes (long holes) at four positions in the vertical and horizontal directions. And the plate 3 facing each other is provided with elongated holes at four corresponding positions in the vertical and horizontal directions, and the bracket 1 and the plate 3 sandwich at least two lattices (bars) 33, It is fixed by bolts 4, nuts 6, flat washers 5, and spring washers 7.

By the way, in the installation method of the satellite broadcasting antenna described above, after the temporary fixing, for example, two grids (bars) 33 are attached to the required height of the grids (bars) 33 by the bracket 1 and the plate 3. The bolt 4 is inserted from the plate 3 side to the bracket 1 side through the elongated hole, and the nut 6 is screwed to the tip of the bolt 4 to fix the bracket 1. At this time, a spanner (not shown) is used. While holding the nut 6 so that it does not rotate in the reverse direction, rotate the bolt 4 in the direction of tightening the bolt 4 with a screwdriver (not shown).

However, in this work, it is required to continuously support the mast 2, fix the nut 6 with a spanner, and rotate and tighten the bolt 4 with a driver. However, it is difficult to perform the same work alone, and there is a problem in simplifying the installation. In addition, the same work will be performed by at least two people, and there is a problem that the installation cost increases.
