[QUOTE="ProDave, post: 364091, member: 6969"] You can diplex two different tv signals into one tv receiver. Not sure why you would want to do that? ther's not much if any difference between different regions. Unless you live on the border and want to have the choice between watching ITV and STV. But you CANNOT diplex or split satellite signals. This is because the power feed from the receiver to the LNB operates in 4 different modes (a combination of different voltages and the presence or absence of a 22KHz tone) this instructs the LNB to receive high or low band and horizontal or vertical polarisation. So it must be one LNB connection to 1 satellite receiver input. As you your LNB if there's no marking then it is almost certainly a quad LNB so 4 outputs, each one intened to connect to one receiver input, and each can independently operate in any mode. If it was a quatro LNB it would say so. they are much less common and intended to operate with a multi switch for a distribution system. Plug it into a receiver and try it. If it works, it's a normal quatro LNB If you want to operate one satellite receiver from multiple LNB's (multiple dishes for different satellites) then you need an LNB switch. Either a manual one, or diseqc if your receiver supports that. [/QUOTE]
