Working properly - no loss of quality to determine when using high-quality connector and cable

We have recently two TVs and an older hard disk recorder, but have at the satellite antenna only a dual LNB available. Because the satellite dish is difficult to access in order to convert to a Triple / Quad LNB had to be another solution. Considering the fact that both televisions are rarely used at the same time I decided after some research for this SAT switcher of Wentronic.

I have the part about 2.5 meters from the LNB away looped into the antenna cable of the first (master) TV set and both before and after connecting the slave TV checked whether a change of the antenna signal can be seen: at individual stations the signal quality according to info display of the TV, although slightly weaker, but even under difficult reception conditions (rain, sleet) is the digital TV picture quality no deterioration observed.

Since use of the SAT switch the strength of the antenna signal is only (in addition to the signal quality) no longer appear on the TV sets - the relevant info box is grayed out. No idea why, but the important thing is that the receiver works in practice.

In addition, I would note that I have a good 4-shielded antenna cable and high-quality F-connector used during installation, and everything was very carefully assembled to keep losses as low as possible. This has paid off here obviously.
