Hi. I want to ask if this antenna http://allegro.pl/antena-35dbi-dual-mimo-4g-lte-ts9-e5573-e5577-zte-i6803399957.html#thumb/1 will help me coverage in the router Huawei B528. I have a speed of about 30 Mb / s, and the range in the router settings has 4 lines. The receiver is about 3-5 km from home. http://www.speedtest.pl/test/166460223
