Where else can you get hi-gain for such a price? – 2.4GHz 7dB SMA Wifi/WLAN/Wireless Network Non-directional Antenna (Black) Reviews

Pros:
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.
Cons:
None whatsoever.
Other:
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.
Bottomline:
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.
