- the occlusion ring 309 includes two parts, one part is a semi-annular structure, which is a first occlusion ring 3091 and a second occlusion ring 3092, that is, the first occlusion ring 3091 is a semi-annular structure, and the second occlusion ring 3092 is a second occlusion ring 3092. It is a semi-annular structure. Screws are pre-installed at both ends of the first shielding ring 3091, and fixing nuts are disposed at both ends of the second shielding ring 3092. The first shielding ring 3091 and the second shielding ring 3092 are fixed to the bottom of the antenna by screws.
- a finite structure 310 is disposed on the flange of the base, the limiting structure is a snap structure, and the inside of the shielding ring is provided with a card slot structure, and the occlusion ring is configured by the cooperation of the buckle and the card slot structure. Fixed to the bottom of the antenna to prevent the occlusion ring from moving up and down.
- FIG. 16 is a structural diagram of the base fixed to the top of the single tube tower.
- the bottom of the base 3042 is fixedly connected with a bottom flange 30421, and the bottom flange 30421 is provided with a sliding slot 312.
- the bottom flange 30421 is fixed to the flange 11 of the single-tube tower top 10 by the third bolt 311, and the third bolt 311 passes through the sliding slot 312 to fix the bottom flange 30421 with the flange of the single-tube tower top 10,
- the position of the three bolts 311 in the chute 312 changes the relative position of the base 3042 to the flange 11 of the single tube tower top.
- the third bolt 311 of the flange 11 with the top of the tower is loosened, and the base station antenna is rotated left and right to rotate the third bolt 311 in the chute 312, thereby realizing the azimuth adjustment of the entire base station antenna.
- FIG. 17 and FIG. 18, and FIG. 17 is a schematic structural view of the integrated pole.
- Figure 18 is a schematic view showing the structure of a split type pole. In order to facilitate the installation and transportation process, it can also be a split structure.
- the pole 3041 includes an upper pole 30411 and a lower pole 30412, and the upper pole 30411 and the lower pole 30412 Active connection.
