ᐅ Conversion of the Satellite System – from Quad to Quattro LNB

Hello everyone,

I’m currently stuck and need your help.

Situation:
I replaced the existing satellite system (quad LNB + splitter + DVB-S receiver) with the following new configuration. I now have the SCHWAIGER "SUN PROTECT - Digital Quattro LNB" and the Kathrein "EXR-158 multiswitch 5 to 8" installed, using the DVB-S2 receivers built into the TV. The satellite dish and the terrestrial antenna, as well as their positions, have remained unchanged. All cables and connectors have been completely renewed and tested (all OK).
Although, according to my understanding, everything should now be correctly connected, nothing works. The TV is not receiving any signal, neither from the antenna nor from the satellite system.

Question: What am I overlooking?

Regards,

For me, the issue was the satellite (SAT) cables. After reinstalling the LNB and so on, it simply stopped working. I then switched all the TVs to internet reception. In the kitchen, it still works with a single LNB. The SAT cables were probably outdated or of poor quality.

But actually, I don’t need satellite anymore. Everything now works over Wi-Fi. It’s also better.

Why was it the SAT cables in your case? I also had them newly installed during the renovation, so this "should" not be the problem.

Since the LNB was replaced, the dish might have shifted slightly, or the LNB may not be properly seated. The distance has changed, and it is slightly rotated, so it is not installed the same way as the old LNB.

If you don’t have a satellite finder, you should get one. They cost about 10 euros.

Have you connected the cables coming from the LNB to the correct inputs on the multiswitch?

Did you make sure that none of the braid wires are accidentally touching the center conductor?

I assume the multiswitch is plugged into a working power outlet.

Have you tried running a new channel scan on the TV with the correct settings?
