The Sierra Wireless 250U has 2 external antenna ports located on it's side. One is for 3G network and the other is for 4G network. The port closest to the front is the 4G port and the port closest to the back is the 3G/4G port.

3G & 4G Antennas

To attach an external antenna directly to the 250u, you will need an antenna adapter (AA359927) listed below. Most dual band (800MHz / 1900MHz) antennas will cover 3G networks. For 4G WiMAX, we would recommend an antenna that covers 2500MHz frequency range as well such as the Wilson Wide Band Log Per Directional Antenna or Wilson Panel Antennas.
