[QUOTE="Analoguesat, post: 55402, member: 176362"] Universal LNB's have two internal oscillators (electronic dohickerties) which are switched by a tone sent up the cable from the receiver. (low band & high band) Early LNB's only had one oscillator, and are not suitable for digital simply because they cannot switch onto the higher frequency band. LNB = Low Noise Block downconverter - they down change the frequency of the microwave signals radiated off the satellite into something that our coax cables can handle. You dont need to know the details, they arent important, just to know that there are two bits of gubbins inside "Universal" LNB's instead of one. Most if not all Universal LNB's will have either UNIVERSAL or "LO 9750 / 10600MHz" marked of them - (could be LO 9.75 / 10.6GHz as these are the same thing). [/QUOTE]
