I had decided on the price and the reviews and the review for these low cost multi-switch. Unfortunately, nowhere was an indication the switch is not capable of this, after all, Quad advertised with HDTV and future-proof multi-switch. This Notice I do not even found in the product datasheet (pdf) on the Smart homepage. I use a TechniSat UNYSAT Quadswitch LNB 0000-8980. Thus, the anger was great was to see no signal on the screens by connecting only the message. Test way taken F-connector and the coaxial cable connected directly and the picture was back. As the cables were now separated had of course her fastest replacement. The local dealer confirmed by the description of the presumption of Smart incompatible with Switch-quads is and fortunately had a kompatibelen and current brands multiswitch since. A good bit over the originally planned budget but OK, the system is now running perfectly. Surely the smart money is on price / performance super default, the processing looks in the original also ok, but further to "in operation" I can not say. Therefore only three stars, 2 deduction for the missing information in the Author's description and for my ignorance bezgl Quatro and Quad. But you can not know everything, or. For all have the Compatible LNB there may be a good buy and worth 5 stars. Therefore my tip: Dear Buyers of multiswitches ... look before buying the type LNB you possess and clarifies whether the desired multi-switch is compatible. In order not Holland-in-distress @ home is :-)
