Using the External Antenna
The WAB-5120 300Mbps 5G Wireless Outdoor PoE Access Point/Bridge provides two reverse SMA
antenna connectors if you prefer to use the external antenna for your application instead of the built-in
directional antenna, please follow the steps below.
1. Remove the two plugs as circled below:
2. Connect your external antenna to the SMA-type connectors at the bottom of the CPE.
Users MUST power off the CPE first before connecting the external antenna to it. Do
not switch from built-in antenna to the external antenna from WEB management
without physically attaching the external antenna onto the CPE; otherwise, damage
might be caused to the unit itself.
Follow the steps described in Connect Up to finish the installation.
