My Condo is about 900 square feet. My wife likes to use her laptop on the kitchen table which is pretty far from my wireless router. Her average signal strength was about 60-70% which I suspected was the cause of the jitter and pausing she experienced while watching streaming video. Also, since there are 9 other wireless networks in range of ours, we experience random disconnects from our router. In an attempt to drown out the neighbor's networks, I bought this Antenna and mounted it up high in the corner of a room in the center of the condo. Amazingly, no matter which room I'm in, my laptops report a 100% signal strength and all the connectivity issues seemed to be resolved, even the jitter with streaming video. I'm pleasantly surprised at how well this antenna works. My only complaint with this product is that the housing for the antenna feels/looks a little cheap.
