Installing the lightning surge protector (Canada)
2. Before you connect the ground lead to the surge protector,
attach it to an approved ground. The recommended wire
gauge is 6 AWG (4 mm). Connect the ground lead to the
building ground. Do not connect to a ground rod or
series of ground rods. If you cannot connect the ground
lead to the building ground, connect it to the steel of the
building. The connection should be no more than two to
three meters. You can also connect the ground lead to the
120 V ac conduit connected to the building ground, but this
is not a preferred solution.
3. Route and connect the co-axial cable from the outdoor
external antenna to the surge protector.
4. Route and connect the co-axial cable from the surge
protector to the appropriate base station BNC connector.
Note: The total length of the co-axial cables from the outdoor
external antenna to the base station must not exceed
10 m.
