ALFA Network's UBDo-nt8 is an excellent choice for an outdoor weather resistant Wi-Fi USB client. It features a 150 mbps 802.11n wireless receiver built into an outdoor weather resistant casing. It contains two mast-o ring mounting rings and a 8 meter (~24 feet) USB cable.
The Ralink RT3070 chipset inside this device is the same chipset that is in the popular AWUS036NH 802.11n USB adapter. In many ways, this is exactly like getting the AWUS036NH adapter inside an expensive outdoor weather resistant casing. The primary difference though is that this device does not have an external antenna connector. Instead it comes with an integrated 12 dBi gain directional panel antenna.
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. It is easy to mount and unmount the adapter if you need to change the placement of it on your RV or truck. Directional antennas are able to concentrate gain better in the particular direction in which they are pointed, resulting in better signal to the access points in that direction compared to an omni-directional antenna of the same gain. However they will pick up fewer access points in total compared to an omni of the same gain since they do not pick up from all directions.
More about the product: This is brand new in retail box. The Wi-Fi adapter is integrated into the outdoor casing, along with the antenna. So there are few parts to take with you. You will get the unit itself, which is the outdoor casing with built-in 802.11n Wi-Fi radio and 12 dBi gain antenna, a 8m USB cable (has mini connector on the end that plugs into the unit), 2 mast-o mounting rings, and software CD-ROM.
