As usual, delivered quickly. Unwrapped, connected two outputs from the satellite multi-switch in the attic to the inputs of the Stacker and the existing satellite transmission to the output. The Destacker in room just to the existing satellite outlet (should actually directly to the cable) and connected to the outputs the 2 satellite cable for the terminal (satellite tuner). And lo and behold: It works !!! Super image on both devices. Works for me also to plug the AC adapter without the least Ackers and without dismantling the satellite aerial socket. I am very pleased and would highly recommend this set without restriction.
