Grounding Water Towers
1. Install all sector ground bars at the top of the tank with stand-off (cherry) insulators and
connect separately with No. 2 AWG stranded insulated wire to a CGB at the top of the
vertical coax run.
2. Connect the upper and lower CGBs by one 4/0 AWG green insulated wire.
3. Install a lower CGB with stand-off (cherry) insulators at the bottom of the tank leg in a similar
manner as on a monopole or self-support antenna tower.
4. In the case of a skirted tank, install the lower CGB in a similar manner with stand-off
insulators mounted to the skirt.
5. Coordinate location with the tank owner and the Field Engineering team.
6. With the permission of the water tank owner, drive two ground rods as close to the tank leg
as possible. Connect the lower CGB to the ground rods using two No. 2 AWG BTCW.
7. Connect these ground rods to the equipment BGR using two buried No. 2 AWG BTCW
along the same path as the coax bridge.
8. If ground rods are not feasible, connect the lower CGB directly to the two runs of No. 2 AWG
BTCW that run along the coax bridge and connect to the equipment BGR. Ground the coax
bridge as previously described.
Note: The local Engineering firm is responsible for the proper design of the ground
system at water tanks requiring special considerations.
New Wooden and Concrete Antenna Poles
Grounding New Wooden and Concrete Antenna Poles
1. Install a BGR that encircles the pole foundation. Construct the BGR in the same manner as
the Itron TCU / CCU equipment BGR except that four ground rods will be installed 90
degrees apart.
2. Connect the pole and equipment BGRs using two buried runs of No. 2 AWG BTCW. These
connections should follow the same path as the coax bridge if possible.
Note: Wooden and concrete poles do not connect directly to the BGR. The BGR will be
used to ground the coax and antennas ground bar at the base of the tower as discussed
later in this document.
Equipment Shelter Grounding
Ground Itron equipment that is installed in shelters the same way you ground a non- shelter site
in terms of equipment ground leads, coax ground kits prior to the Itron TCU / CCU equipment
jumpers, and MGB placement.
