Query: Works Great. Strong signal after installing this at HOME

I am an AT&T customer and was getting only one bar with frequent dropped calls or sometimes no signal in my apartment room. But outside my apartment, I had 1-2 bars. I installed this antenna on my glass window. WOW... it gives me 3-4 bars and no dropped calls. The signal is weak only if it is rainy outside. Great buy if you are in similar situation.
