arjxh56 Posted May 27, 2014 Share Posted May 27, 2014 My friend has a new to him (used) motorhome and asked me to hook his new Cello TV and Dome Satellite up. The Sat dome has 2 cables coming down, assuming a twin LNB, and his TV only has a single satellite input. When I connect just a single LNB cable form the dome to the TV I get reception and the automatic search finds around 300 stations, but the dome is still whirring around like its still looking?? When i use a separate satellite receiver with 2 inputs, such as the sky box, as soon as both LNB cables are plugged in the dish stops and is quiet as a mouse. This makes me think the Dome is only happy when both LNB cables are in use at the same time. My questions are.... 1. How can i stop the dome whirring away when only connecting a single cable into his Cello TV? 2. Should it be whirring like this when using a single LNB cable, or is it a fault? Many Thanks Link to comment Share on other sites More sharing options...
colin Posted May 27, 2014 Share Posted May 27, 2014 Just a thought, has he tried swapping which half of LNB cable is used? Link to comment Share on other sites More sharing options...
arjxh56 Posted May 27, 2014 Author Share Posted May 27, 2014 Hi, Yes I have tried both cables for him and it didn't appear to make any difference? Link to comment Share on other sites More sharing options...
Dave Newell Posted May 27, 2014 Share Posted May 27, 2014 Which make of dome is it? There are now several different types around all of which work in slightly different ways. D. Link to comment Share on other sites More sharing options...
arjxh56 Posted May 27, 2014 Author Share Posted May 27, 2014 I cannot recall which one it was. I will call him in the morning to check. I assumed (but could be wrong) that all LNB's worked in the same way as they're sold as universal items in places such as Maplins? Saying that, i guess any software / firmware in the satellite unit could be playing a part... I will check the brand name and come back to you, Thanks Link to comment Share on other sites More sharing options...
