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 11. Avoid over-tightening.

The antenna must be vertical to the ground to achieve the optimal signal receiving.

On a dual-3G MSR 930-DG router, the SIM1 (supporting CDMA2000) and SIM2 (supporting

WCDMA) cards are associated with the antenna connectors on the front and rear panel, respectively.

When you install a 3G antenna on a dual-3G MSR 930-DG router, choose the correct connectors.
