I live in a condo in downtown Toronto, with an obstructed view of the CN Tower.
Previously, I was using a $20 Philips indoor/outdoor antenna which didn't provide vary reliable reception. The FL5500A FlatWave greatly improved signal quality and even allowed me to pull in [several] additional stations, for a total of 23 channels.
Can cheaper antenna provide the same results? I can't say but I can say that I'm entirely satisfied with the Winegard; it met my expectations...and then some. 11 HDTV channels for a fixed cost of $100?!?! That sounds worth it to me.
