Installing a 3G antenna
One 3G antenna per 3G module is provided with the router. Purchase one if you need to install two
antennas.
When you install the 3G antenna, attach the antenna to the port marked "MAIN."
To install an antenna:
1. Adjust the angle of the antenna to 180º.
2. Attach the antenna to the router, as shown in Figure 10. Avoid over-tightening.
The antenna must be vertical to the ground to achieve the optimal signal receiving.
