Do parabolic signal boosters work?



This is my first test with the Skyreat parabolic signal boosters. Did it help boost my signal any?

I plan on doing 3 or 4 more test with these signal boosters before giving a final verdict on them. Stay tuned. I am not knocking them or disclaiming they don't work, I am just showing my results. Maybe I did something wrong? I understand the trees work as obstacles, that is the purpose of me trying to find something to boost the signal! If you have any opinions of what I could do or try for better results please leave a comment below.

You can purchase these on Amazon for only $19.99: http://amzn.to/294h41p
