As a solution, I bought the JULTEC JRM0516T. This consumed in the current version for all 16 participants only 40mA (models before 2014: 70 mA). To ensure that all appliances worked again easily! Differences in image, sound or signal strength I could not make out - but since the TechniSwitch certainly was already at a high level.
The JULTEC has been completely developed and built in Deuschland. He is clearly valent built as the Technisat. The heavy and robust housing provides a very good quality impression. The slightly higher price is more than justified, I would buy this multi-switch again.
With one or two JRM0516K can extend the multi-switch on a 32er or 48er system!
However, I would hope that such devices are slightly larger, so that between the individual connections a bit more space for attaching the satellite remains cable.
