Thinking of getting either the SRC or the Alfa. I am impressed by Ubiquiti's sensitivity rating but only on paper. Sensitiviy and power in G speed best the Alfa. However, in real life testing it seems to be worse. According to my research I came up with the following links supporting this belief below:

I like to hear others who have own one or both (Ubiquiti and Alfa500) to see if in their experiences of using both has bear out dismal results like the above links or is it totally opposite?

Please list what cards you owned and are comparing the Ubiquiti SRC to if not the Alfa.
