Longer Range than the average WiFi Extender - 2.4 GHz.
The Long Range Super USB WiFi Antenna 3 can be the best WiFi solution for home, mobile, RV, student and travel. It plugs into your PC computer's USB port for a powerful WiFi Internet reception. On average you can get 300 to 400 feet even through several walls. Performance: Most people can watch Netflix in HD quality with the Super USB 3 in an average situation. In an extreme line-of-sight test with no obstructions we connected to a network one mile away but speed was significantly reduced.
The Super USB 3 is best suited in a less WiFi crowded area as might be found in the country for a guest house, barn, end of a road or large home. The USB-3 uses 2.4 GHz which is longer range than other bands. (In a WIFI crowded "city" type area 5 GHz is usually a better choice). You can use the 2.4 GHz CC Vector "Extended" Long Range WIFI Repeater System in a WiFi congested area because the narrow beam antenna is not as susceptible to interference.
