More about the integrated 12 dBi gain directional antenna: Please keep in mind that because it is directional, you want to set it up to point in the general direction of the access point to which you want to connect. Instead it comes with an integrated 12 dBi gain directional panel antenna. The primary difference though is that this device does not have an external antenna connector. In many ways, this is exactly like getting the AWUS036NH adapter inside an expensive outdoor weather resistant casing. The Ralink RT3070 chipset inside this device is the same chipset that is in the popular AWUS036NH 802.11n USB adapter. It contains two mast-o ring mounting rings and a 8 meter (~24 feet) USB cable.
It features a 150 mbps 802.11n wireless receiver built into an outdoor weather resistant casing. ALFA Network's UBDo-nt8 is an excellent choice for an outdoor weather resistant Wi-Fi USB client.
