This LNB is from the Ultra series with an extremely high signal amplification. There is a risk in coming to high level range, which can lead to overloading of the receiver input, provided that the cable runs are not quite long and / or you are in the border area of satellite reception. Under normal conditions, an LNB from the Premium range is sufficient which leads to better results. The characteristics of this LNB and here above all the poorer signal quality under normal conditions should be stated absolutely in the product.
For me, the LNB was used in the motor home with a 10 m cable, which led several transmitters to poor transmission quality and failure. When I increased the lead gradually to up to 40 m, the reception quality was getting better rather than worse, which is why the part was useless for me.
