As the factory antennas are mostly 2dBi rubber ducks which are packaged with the wireless routers or PCI WiFi devices pretty much the same way as low-cost tyres fitted in a new car for obvious reasons, the full potential of wireless coverage cannot be exploited without fitting in stronger antennas. Simply unscrew the factory antennas and replace them with these +9.5dBi Omni antennas. If your wireless router is amongst one of the few which has undetachable antennas, you may drop us a message for further advice. Instantly delivering a gain of x9.8 on each antenna to improve the speed and the range of your wireless connection. The +9.5dBi Omni is slim, lightweight and having a length of merely 15 inches. It works beautifully with any 802.11b/g and 802.11n MIMO WiFi devices.

Most routers and WiFi cards some with a +2-6 db gain antenna. This one is +9.5 db. The difference is +3.5-7.5 db. Where does that gain come from?
From making the RF pattern less omni-directional and more unidirectional. That's where gain comes from: by focusing the radiant energy in a particular direction. At the expense of gain in other directions.
That's why routers come with low gain antennas. The radiation pattern is like a sphere with the factory installed antennas. The radiation pattern of this particular antenna is probably more like a donut.
And donuts have holes. That's why it's entirely possible to get lower performance from this antenna than the factory original in a particular application: the devices may be aligned on a null with respect to this antenna's particular radiation pattern.
This is an inexpensive antenna. It's a good replacement for a lost one. If you are trying to get better WiFi communication between devices, however, be prepared to experiment with device placement.
Four stars because this is a good antenna. It's not a miracle worker, though! :)
These gave me a little boost, just what I needed. I use mine vertical and have no problem with them rotating over. They did shift the center of gravity on the router more to the rear. Make sure they are tight and they should work vertically. Like any antenna if you have 'no signal' these won't help but they do boost a bit.
Gonna use this set up with a Range Extender Amped Wireless High Power Wireless-N Smart Repeater and Range Extender (SR300) with extender antennas Trendnet 7dbi Indoor Omni Antenna (tew-ai77ob) - to get to the 'radio/computer barn'. I use an X10 Appliance AC plug to turn the Extender off when I don't need it so not to bug the neighbors wi-fi.
I like it because it was inexpensive, and met my needs: It increased the range and strength of my wireless network enough that the neighboring APs on my block did not keep stealing and overlapping channels with my network. 802.11b/g/n networks operating on the 2.4GHz band only have (in the US) 3 channels (1,6,11) that do not overlap one another. Before, I would have full bars and rates for my WiFi connections, but the routers of my neighbors did not hear mine and continued operating on the same channel as my network; interfering with my WiFi and leading to a large portion of dropped packets on my network. It was bad enough that I could not watch streaming video.
I feel that the product would have been better if it were dual band (for a similar price, and the same signal gain), and/or came with one of the magnetic base mounts with an SMA wire that similar items include.
I would recommend this product to anyone foreseeing themselves sticking to a 2.4GHz WiFi network for a while, and needs to increase the distance and strength of their signal.
Cons: Product arrived in an air pack flexible envelope. Chances for product damage are high. These antennas will not fit an unmodified Buffalo router, nor any router with recessed antenna ports. With no options for expedited shipping it took three weeks to find that they in fact do not fit my application despite listed as being Buffalo compatible. These have a THICK threaded steel connector on the base that prevents them from begin screwed into an older WHR-HP-G54 router/AP.
Despite this, they *are* RP-SMA antennas. I just wish the product details made their dimensions known. (Especially on connector exterior diameter) The antennas are useless unless I make heavy modifications to my wireless router or extend the external antenna port with an SMA pigtail. Overall, I am not satisfied with the product as received and their inability to be used directly in application as described.
