Worked for me

I took on the task of setting up a network in my mother-in-law's house. She has a desktop on the 2nd floor and a laptop in the basement. I took the wireless router she had (BEFW11s4 v2 I think) and placed it on the second floor to connect directly to the desktop. Using the laptop, I found the signal strength to be 0-1/5 on the 1st floor and 0/5 in the basesment. After adding these antennas the wireless range increased dramatically. It is now 5/5 on the first floor and 4/5 in the basement!!!!! Made my job incredibly easy. Only downside is the price, came out to be about $63 from BestBuy.
