I just only very difficult to do with this antenna. Many locations in the house on the floor and tried out. The success was moderate. After I had my concerns to my provider after the location of masts and antenna have mounted and aligned outside the chimney, I am very satisfied with the performance. Transmission tower is approximately 4.0 km away. But in between with forest. While on the router are only two or sometimes three strokes of the field strength, but the measured Leisung rose to 22.0 to 28.0 Mbps in the download area of approximately 6.0 Mbps. The Upload area to now 10.0 Mbps. Comes almost ran to the services of my provider. Therefore highly recommended antenna.
