This is one of the best home, mobile, or RV WiFi Antennas made. The Super USB WiFi Antenna 3 plugs into your computer for powerful WiFi Internet reception. Installation is a snap and performance is outstanding. While testing it in our small town of Fortuna, California we were able to see an additional 20 wireless networks. On average, users can get 300 to 400 feet even through several walls. In further tests we were able to connect to a small wireless router from over 100 yards away, keeping 80% signal strength through several walls and obstructions. In one of our tests we even connected to a network a mile away. You may be surprised at what the Super USB WiFi Antenna 3 can do for you. The antenna incorporates a water resistant design for outdoor use (IP65 Rated), along with wireless “N” technology for lightning fast file transfers with your “N” router. It comes with a 15-foot USB split cable that offers two plugs to your computer, although normally one plug is sufficient for powerful reception. The antenna mounts easily to a window with suction cups or to the wall using the lanyard and "hook and loop" mounting strip. If you are trying to receive a very distant signal from outdoors, then the best place for mounting the antenna is above the peak of your roof so that signals can be received from miles in every direction. A cable tie is included for pole mounting outdoors. You can purchase an additional 30-foot USB cable so that you can mount the Super USB WiFi antenna on a roof, a mast or in a window. Compatible with 802.11 B, G, and N. Up to 150 Mbps. WEP, WPA, WPA2, WPS encryption compatible. Easy software included. Works with Microsoft Windows - XP, Vista, Vista x64, Windows 7, Windows 7 x64, Windows 8, Windows 8 x64, MAC OS 10.4-10.8. Note: The Super USB WiFi Antenna 3 requires installation of software drivers. Gaming stations such as the Xbox® and the Sony PlayStation®, the iPad®, iPhone® and Android® devices are not capable of installing these software drivers.
