I have the Fuba DAA 850 A satellite dish installed 414 Quattro switch LNB in conjunction with the Fuba DEK and have to say that the investment has paid off, interference-free reception with 19% profit as opposed to the same old system size. The assembly and installation was for me, I've done something like this for the first time himself, simple and self-explanatory. Am absolutely satisfied and recommend that mirror with a clear conscience.
