Good satellite distributor

Bought the distributors, because I have a satellite receiver in the hard disk recorder and in addition to normal receiver. Working properly, the transmitter can (both simultaneously visible thanks PIP on TV) switch back and forth, turn even the same channels on both devices and see at the same time. The signal power remains stable. If one of the devices is running and the other is turned on, a pixel formation is jediglich in switching torque available. But that should not really be a drawback well.
