Good little LNB, works perfectly, the difference with my old head is unfortunately insignificant despite a rowdy name "3D HD etc" which means absolutely nothing, an LNB only receives a signal to be processed by a demodulator, and it is one that will have the capacity or not to use the said signal in HD to SD etc ... On the other hand the gain of 70 dB seems to me quite excessive and sensationalist. Finally good little head with a excellent value for money but it is not the panacea announced.
