This is one of the best home, mobile, or RV WiFi Antennas made. Just plug it into the USB port on your computer for powerful WiFi reception. We have incorporated the newest WiFi wireless "N" technology with a connection rate up to 150Mbps for lightning fast file transfers.This antenna comes with a special USB split cable that offers two plugs to your computer to increase power. Normally one plug works well for a powerful reception. If you need more powerful reception and you have an extra USB port, then plug both into your computer.It mounts easily to your window with suction cups or to the wall using the supplied lanyard and "hook and loop" material. If you are trying to receive a far away signal from outdoors, then the best place for mounting is above the peak of your roof so that signals can be received from miles in every direction. This antenna is made weatherproof, while bouncing harmful UV rays. A standard 15-foot split USB cable is included but you can purchase an optional 30-foot USB cable to reach the peak of your roof. Outdoor mounting is easy with the included cable-tie to secure the antenna to your plastic pole.While testing it in our small town of Fortuna, California, we were able to see more than 25 different wireless networks and even connect to one over a mile away! Normally, we could only see about 6 networks within range. 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. You may be surprised at what the Super USB WiFi Antenna-3 can do for you.Compatible with 802.11 B, G, and N. Up to 150 Mbps. WEP, WPA, WPA2, WPS encryption compatible. Easy software included.
