Seems to be working so far; have it in one position and most of the local HD signals come thru. Don't have HD programming through my satellite service, and have to say the local HD from the antenna is a superior picture on my HD LCD TV. I have 2 antenna connections on the back of my TV, one for over the air, one for satellite box, so I can switch easily back and forth. Don't have anything to compare as this is the only HD antenna I have used, but the picture is very clean when the signal comes thru.
