A monoblock LNB is a simple way to receive Astra 19.2 and Hotbird 13 with one antenna. In order for the connected receiver to know on which "eye" which satellite is being received, the DiSEqC settings must be set correctly in the receiver menu. Many monoblocks receive Hotbird on DiSEqC A or 1 and Astra on DiSEqC B or 2. There are also models on the market which are reversed. In this case, the settings must be adjusted accordingly.
