Installing An Rru On A Pole; Requirements For The Vertical Deviation Angle Of An Rru - Huawei RRU5909 Installation Manual

RRU stacked installation. When the horizontal distance between the main and auxiliary poles on
a tower is greater than or equal to 810 mm (23.62 in.), the side-mounted mode is recommended
for installing RRUs on the auxiliary pole to meet the minimum clearance requirements.
Otherwise, the standard mode is recommended for installing RRUs on the auxiliary pole.
•
RRU stacked installation is not allowed in indoor scenarios.
•
RRU stacked installation is allowed only when installed on one or more poles in outdoor
scenarios, and a maximum of three RRUs can be stacked installation.
•
The periphery of RRU5309w external antennas should avoid metal shielding (such as wirelines
of the cable tower, metal fence, ground bar, and billboard).

When the operator faces the RRU whose handle and cabling cavity are on the right-hand side, the side facing the
operator is the front of the RRU, and the other side is the back of the RRU.
