B.3 Tower Ground Construction
1) Install a Tower Ground Bar (TGB) that will be used to ground a feeder cable onto the tower.
If the height of the tower is more than 65.62 ft (20 m), two or more TGBs should be
installed (onto the lower and upper sections of the tower). If the tower is 65.62 ft
(20 m) or less, one TGB should be installed. Since the TGB installation location and
the number of TGBs to be installed can differ depending on the system environment
and provider’s standards, consult your service provider.
2) Each TGB should be grounded and separated from other grounds. If there is an
existing ground bar or ground cable for TGB, install the TGB by branching from it
using a ground cable (AWG2, GV 25 mm

3) Fasten the Ground Kit (feeder cable grounding assembly) to the TGB ground terminal
and the tower hole using the pressure terminal hole attached at the end of the ground
kit’s ground cable.
