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.
