Pole mount grounding
Each RRH cabinet must be grounded.
Each RRH cabinet must be grounded as follows:
• At the top of the cabinet
• At the left or right side of the cabinet.
The figure below shows how 2 AWG ground cable can be routed, along the pole, from the
RRH to the ground rod.
Important! For antenna sharing/daisy chain installations (two RRHs per sector), a
grounding bus bar must be installed within 6 feet of the RRHs, to ground the antenna
sharing surge protector.
