I can only agree with the positive reviews. I had previously (left cable is difficult to clamp) an aerial socket of a producer --- switch with this reception I had problems and the installation was suboptimal What I 84 Aerial socket like about Kathrein ESD: - Good in my eyes cable clamping solution with stable metal cap - Clean Shielding: under the cover cap are a lot of little springs, the fail-safe connecting the lid and the housing together. - The reception is very good
