twin out LNB - 2 power supplies or one ?

**dmm** · 01-11-2004

hello,

i have a skystar 2 PCI card and a GBSAT receiver and one (twin output) LNB - OK its obvious that each of the LNB outputs will go to Skystar and GBSAT respectively - but the question is - must i disable one of the power supplies to the LNB - i.e for instance will the power supply coming from the GBSAT receiver be enough to power the LNB and enable it to supply a signal to the skystar PCI card also ?

thanks

Both receivers must supply one of the LNB's with power, just as if it were two seperate LNB's on two dishes.
