I have to buy two, one works very well and gives very good result, but the 2nd was stillborn, I have not been replaced since the post is 20 terminals and return home would have cost more expensive than recommend another. It's still crazy as it is not controlled before the sale! In short I am moderately satisfied with this purchase. On my first amp, the gain made me pass reception power 36% 56% anyway. (85cm dish)
