7. Using a plumb line or bubble level, ensure the antenna is within 5° of vertical
(perpendicular to the horizon), and tighten the mounting bracket bolts.
8. Bolt the lightning suppressor mounting plate to a flange that is attached to a valid
earth ground. The roof ring ground system, a Central Office grounding plate, and
building structural steel are examples of valid earth ground points. If the
mounting plate cannot be bolted to a valid earth ground, bolt the mounting plate
to a point within 15 feet (4.6 m) of the chosen valid earth ground. If the mounting
plate is to be installed in a nonmetallic junction box, perform the installation and
bolt the assembly near the chosen valid earth ground.
9. Assemble the lightning suppressor as shown in Figure 3-22.
Figure 3-22. Assembling the Lightning Suppressor

suppressor, and from the lightning suppressor to the cable entrance into the
building.
Note: A junction box must have inside dimensions of 7 cm by
7 cm by 4 cm to hold the mounting plate and attached
components.
