If you have been in the market for an outdoor weather resistant Wi-Fi client, the new UBDo-gt from Alfa Networks is an excellent choice. It features a 1000mW wireless receiver built into an outdoor weather resistant casing. It contains two mast-o ring mounting rings and a 5 meter (~16 feet) USB cable with a special dual-Y USB connection end that goes into your computer (features both a power/data connector and a secondary power-only connector so that you can use 2 USB ports on your computer to provide full power to the device without needing an external power source for it).
The Realtek RTL8187L chipset inside this device is the same chipset that is in the popular AWUS036H long range 1000mW USB adapter. In many ways, this is exactly like getting the Alfa AWUS036H 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. Personally I find an integrated antenna the best option for basic travel needs, so you do not have to lug around a heavy external antenna and worry about assembling/disassembling it when you are ready to hit the road. Because this is 12 dBi gain, you will get better performance compared to an 8.5 or 10.5 dBi outdoor external antenna anyhow.
