Previously, I had tried a satellite distributor of Hama. The clear advantage here: it both devices could be operated at the same time, if it was in program choice to the same plane of polarization. Disadvantage: there is permanently installed in the television on a receiver can, this is not off and always sends thus a program selection. Therefore, I had to pay attention because it always, previously to select the TV the correct channel, otherwise no signal arrived (polarization plane problem) when sky receiver. For me, it was found that this was not really practical for me. So I decided then but for the switch with built up.
The switch is very solid built and the quality pleasantly surprised me. The function is described: it is just a signal to time. To ensure that no device is disturbed / affected by the other receivers. The change-over I do not feel to be too large; is just a mechanical switch.
