And a technique for fixing it is disclosed.

In addition, as shown in FIG. 1, the wireless base station antenna for mobile communication has two frames horizontally connected to two frames horizontally, and a bolt hole is formed in the frame to fix the antenna equipment.

As such, fire hydrants and wireless base station antennas are installed very little inside the tunnels, and they are installed separately. They are also fixed to the wall of the tunnel through a simple structure bracket that does not need to be changed directly or in any position.

However, due to the development of the Internet and wireless communication, only a large number of telecommunication companies providing wireless Internet or wireless communication (cellular phone) services reach only three places. In recent years, radio waves such as radio and digital broadcasting can be received in the tunnel Communication antenna equipment of various kinds and sizes is installed.

As shown in FIG. 1, the various communication apparatuses are fixedly mounted on a frame vertically connecting two frames arranged vertically. Since the sizes of various communication antennas are not identical, The distance between the left and right frames, the spacing between the left and right frames, and the spacing between the bolt holes are changed. Therefore, it is difficult to install various communication equipments in one cradle.
