Methods: I tested my current indoor antenna while attached to a Samsung TV, which has the strongest receiver of any of the TVs in my home. I first scanned for channels with my current antenna attached. I then disconnected my antenna and immediately attached the Winegard FlatWave. I oriented it in the same direction used for my current antenna, which is toward the closest major city (about 30 miles away). I also placed the FlatWave as high as possible in the room. I then re-scanned for channels.Results: My original antenna picked up 31 channels. The Winegard FlatWave picked up 12. The difference is that the Winegard antenna picked up only stations from the direction the antenna was pointed, while my current antenna also picks up stations from 3 nearby cities in other directions.Discussion: My current antenna is a DB4 multi-directional type and much larger than the FlatWave. Considering the size of the FlatWave, it performs very well. Depending on the direction the FlatWave is pointed, you will pick up any nearby stations within your area, but just not at the same time.Conclusion: The Winegard antenna does what it says it will do. It picks up stations within the distance specified (actually a little further) and along the orientation direction. However, my current antenna is multi-directional and picks up stations that are twice as far and in various  directions. It is not surprising that it performs better, but I was very impressed by the FlatWave.
