Alfa Tube-U(G) 802.11g outdoor long range USB CPE adapter (N-male)

Alfa Tube-U(G) is a long range outdoor Wi-Fi USB adapter for Windows computers. It is great for marine and RV use. If you are a into boating, own an RV, or just need a good long range outdoor Wi-Fi adapter at a low price, consider Alfa Network's Tube-U(G) model, a 500mw 802.11g outdoor wireless USB receiver with N-male external antenna connector. Tube-U(G) is light-weight and easy to mount (it is 4.1 ounces and just over 6.5 inches tall). Simply use the two included mounting ties to fasten it to almost any type of infrastructure. Tube-U(G) will work better with 802.11g access points compared to our Tube-U(N) 802.11n model. That model will work faster/better with 802.11n standard access points though. Right now, 802.11g signals are more common.

Easily fasten it to your boat or RV, or an outdoor pole or post. It has weatherproof casing and it comes with a special shielded 5 meter (16 feet) USB cable that is designed to prevent against power loss. Compared to a standard USB cable, the shielding is almost twice as thick. This allows you to mount this item further away from where you will be using your computer. You can connect any type of antenna to this product that has an N-female connector on it. We also sell pigtails and converters if you already own an outdoor antenna with a different connector type.

A great antenna for outdoor use would be Alfa's 15 dBi antenna, model AOA-2415, seen here.

In the picture to the left we have it displayed with our 8 dBi model. You can save when purchasing this item together with our 8 dBi antenna by going here.

This product does not come with an antenna, and does require one to operate. You will need to purchase or already own a compatible antenna to use this. It does not have any type of internal antenna, and indoor use is not recommended. For indoor 802.11g Wi-Fi, we recommend Alfa model AWUS036H.

This product is an 802.11g standard Wi-Fi adapter with top speeds of 54 mbps.
