Unless your friend bought some obsolete equipment the LNB should have two
connections. I haven't seen single connection LNB's in over 8 years from any
vender. You can't split a single coax due to polarity input from the
receiver 13vdc and 18vdc. A dual LNB dish only means that the dish has two
LNBs. One for the 101 bird and the other for the 119 bird. A triple LNB adds
the one for the 110 bird. If your friends LNB only has one coax connection
tell him spring for a new LNB. You can pick an RCA branded LNB at Walmart
