Grounding Equipment Stored in Shelters
1. Connect the internal MGB to the equipment BGR using two No. 2 AWG BTCW ground
leads.
The BTCW can penetrate the wall or foundation of the shelter in two separate holes. Refer
to the shelter manufacturer specifications for placement and quantity.
Note: Whenever ground leads penetrate concrete, they must be protected by PVC
conduit.
2. At a location just outside where the coax penetrates the shelter wall, install coax ground kits
and connect to a CGB.
3. Bond the CGB directly to the BGR.
Repeaters on Communication Tower Sites
Repeaters at collocation sites must have antenna mounts, coaxial cable, and coax bridges (if
required) grounded in the same manner as a full network device.
Grounding Repeaters on Communication Tower Sites
1. Locate the MGB at the repeater equipment location and bond to the existing ground system
at the site with two No. 2 AWG BTCW leads.
2. If no existing BGR exists or it is not practical to connect to the existing BGR, drive a single
ground rod adjacent to the repeater equipment to serve as the ground electrode system.
3. Bond the ground leads from the repeater equipment and the coax ground kits, immediately
adjacent to the repeater, to the MGB.
CCUs and Repeaters on Utility Poles
CCUs and Repeaters mounted on utility poles will be grounded using a single ground rod
located immediately adjacent, if possible, to the utility pole.
Grounding CCUs and Repeaters on Utility Poles
1. Connect the ground lead from the repeater, coax, and antenna mounts (if applicable) to a
common MGB located below the repeater.
2. Bond the MGB to the ground rod using one run of No. 2 AWG BTCW.
3. If any antennas are located on different structures than the repeater equipment, the antenna
mount (if metallic) and coax ground kit will be bonded to a CGB located to permit optimum
ground lead connections.
4. Bond the CGB to a single ground rod located immediately adjacent to the support structure
using No. 2 AWG BTCW.
Note: In all cases, ensure that the grounding design complies with the utility pole owner’s
requirements.
