Tried this unit out and its heading staight back to Best Buy. It certainly does pick up local HDTV signals without its power booster, and picture only improves slightly with the booster plugged in. Reception was never completely clear for six local channels, and my non-Hi Def signal from my Dish was vastly better than the over-the-air signals using this antenna. It got two stars because it's slightly better than no antenna at all.
