Interestingly, the antenna has brought only 1 line of recording according to my Internet Manager software, which I was skeptical at first. But when I surfing and speed tests have tasted, hats almost bowled me:
Internet speed (download) without antenna: approx 0.3Mbit / s (that actually hardly use)
with antenna: in the range 5-9 Mbit / s!
When uploading, it is no different. So who might only further inside the house has a bad reception or a bad speed at which the antenna fully paid out!
Hab incidentally comparatively also tried the stick alone in greater detail to give to the window, which has, however, much less brought.
Conclusion: 5 *, the thing hats on it!
