Figure 3-24. Assembling the Lightning Suppressor
10.Install 1.5 inch (3.8 cm) nonmetallic conduit from the antenna to the lightning
suppressor, and from the lightning suppressor to the cable entrance into the
building.
11.Install a user-supplied bracket, preferably non-metallic, to support the vertical
section of conduit to the antenna.
12.Route the antenna cable through the conduit, and connect the cable to the
lightning suppressor. See Table 2-4 for specific cable lengths.
13.If the lightning suppressor is not mounted directly to a valid earth ground, crimp a
length of 4.115 mm (6 AWG) ground cable to the two-hole terminal, slide the
terminal over any two of the three threaded posts on the lightning suppressor
mounting plate, and attach the terminal to the mounting plate with two KEPS
nuts. Use the two posts that allow the least bending of the cable.
Note: A junction box must have inside dimensions of at least 7 cm by
7 cm by 4 cm to hold the mounting plate and attached components.
