Bought 3 of these for my 802.11n router The signal reception improved a lot, finally the wifi reached through all of the house and transfer rates improved too (thanks to the better signal reception) If you have an access point with a small antenna and you need to improve the signal, this is a simple way to do so. I don't know of anywhere else where you can get +7Dbi or higher antennas for such a low price.
Keep the antennas at least 10 cm away from each other at all time. The length of a wifi 2.4Ghz wave is 100mm. Bring the antennas closer to each other than 1 wavelength and the router or AP's wifi chip has a good chance of overheating. This has nothing to do with these antennas. It's just physics. Every wifi device has this problem.
Get one (or more) of these if you can't afford expensive high-powered wifi equipment but still want to improve the signal reception on your router. Note: this is RP-SMA, which is the standard connection on most routers and APs. Don't buy this if you use Linksys equipment. Linksys routers and APs use a different connection.
