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.

There must be two power supplies to the twin lnb........so that one reciever can "ask" for horizontal frequencies at one voltage.....and the other receiver can "ask" for vertical frequencies at a different voltage....otherwise how would the lnb know?.................................
