Figure 3-5 Diameter of a pole
NOTICE
•The diameter of a pole for installing an RRU ranges from 60 mm (2.36 in.) to 114 mm (4.49 in.). The recommended diameter is 80 mm (3.15 in.).
•When the diameter of a pole ranges from 60 mm (2.36 in.) to 76 mm (2.99 in.), a maximum of three RRUs can be installed on the pole and the side-mounted installation is recommended.
•Only a pole whose diameter ranges from 76 mm (2.99 in.) to 114 mm (4.49 in.) supports more than three RRUs.
•The recommended thickness of the pole wall is 3.5 mm (0.14 in.) or above.
Figure 3-6 shows two RRUs installed in centralized mode.
