12.Route the antenna cable through the conduit, and connect the cable to the
lightning suppressor. See
lengths. Connect the other end of the cable to the antenna.
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 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.
14.Connect an RG58 (060-72010-xx) cable between the lightning suppressor and
the TimeSource 3100. See
lengths.
