Discharge Units should be placed on the base of the antenna and at the point where the
antenna lead (typically coax) enters the site equipment building. When a modem is used, a
lightning arrester should be placed at the point where the phone line enters the site
equipment building. If you use a modem (manufactured by other than BBI) it is
recommended that you also install a surge suppressors or lightning arrester on the phone
line as close to the modem as possible. Any unit interfaced to a radio or modem must be
connected to a known good earth ground.
5.2.10 Secure Wiring Connections
Make sure that all wiring connections are secure. In time wires that were once round will
become flattened due to the pressure applied by screw compression type terminals and site
vibrations. After a while these compression screws have a tendency to become loose. Part of
a good maintenance routine should be to check and tighten all screws associated with
wiring terminal connections. Avoid nicking the wire(s) when stripping insulation.
Remember, nicked conductors will lead to future problems. Also remember to provide some
cabling slack and strain relief.
If installing stranded or braided wiring that has not been tinned, be sure to tightly twist
the end (in the same direction as manufactured) and then trim off any frizzed wires.
