I had no illusions about what this could do, I know how broadcast works and could see right through their commercials. But I've been on Rabbit Ears for the past few years and victim to changes in Weather, Cars driving past my window, and neighbors walking around upstairs. Consumer Reports reported that Amplified Rabbit ears do better. I got a set from Radio Shack and only got a slight improvement.
A Neighbor loaned me his clear TV said he was getting great results from it. The real noticeable difference is in putting it against the Wall, you get less inside interference and therefore a few more channels with less breakup. You wont get (nor was I expecting) Hundreds of channels or anything. I just wanted the lower band (2-10) with less interference and I'm getting it. Their advantage is a longer cable to run to the wall or window and eliminating some of the inside interference. Nothing More.
Bottom Line: Yes, I would recommend this to a friend
