Installation Instructions

Use the following guidelines when installing the antenna:

  • Identify a proper surface to place the antenna. The Cisco logo must face upward, towards the sky.

  • Clean the surface of the mounting location before mounting the antenna.

  • Remove the adhesive tape from the back of the antenna and press it firmly to the mounting surface.

  • Using a properly calibrated torque wrench, attach the antenna SMA connector to the port of your device. The standard mating torque for SMA connectors is 3 – 5 in-lb (0.3 – 0.5 N-m).
