a video describing the 2 wireless antennas : the cantenna and the biquad . the test is at home conected to a wireless network that is very near . you will se the basic biquad antenna and the tipical cantenna. there ar some comparitions betwen the antennas . the cantenna is directional , making it ideal for point to point conections . the biquad is larger in the angle that radiates the WIFI signal , making it ideal as a antenna for a sectorial WiFI antenna site . I had internet and still got it for some 1 and a half years trough the antennas that is in this video :)
