There is a difference.

Figure 15 is a perspective view showing the installation process of a wireless unit according to an embodiment of the present invention on a support pole.

The process of installing the wireless unit (RU) on the support pole (P) using the clamping device 100 for the support pole of the wireless unit according to an embodiment of the present invention configured as described above will be briefly described as follows. .

First, as shown in (a) of FIG. 15, install the upper clamp (100A) and the lower clamp (100B) and the hose band clamps (10A, 10B) on the support pole (P), and install the hose band clamps (10A, 10B) on the pole side clamp (110). It is fixed through the band fixing hole (117).

At this time, the vertical distance between the upper clamp 100A and the lower clamp 100B should be adjusted to correspond to the vertical distance between the upper and lower wireless unit side clamps 120 to be fixed to the wireless unit (RU) mounted thereon.

Then, the wireless unit side clamp 120 is passed through the bolt through hole 125 formed in the wireless unit side clamp 120 using the fixing bolt 127, and the bolt fastening hole formed on the rear surface of the wireless unit (RU) is connected. It can be fixed by fastening it to RU-25).
