Of course, the purpose of adding an upgraded antenna is to vastly increase the range.

Most wireless cards have an RP-SMA (female) antenna jack, for attaching an external antenna to boost your signal.   All of the Alfa USB adapters in our site have an RP-SMA female jack.

If the distance to the Wireless Access Point’s antenna is more than 300 feet, you should consider upgrading your external antenna.  Without an upgraded external antenna, you may have issues with the signal fading out sometimes.   To place the antenna in the best position for direct line-of-sight:  Use an outdoor enclosure for the USB WiFi adapter and USB extension cables to reach from the enclosure to your PC.
