Wi-Fi antenna how to choose

Question

WiFi

So, there are a bunch of antennas:
www.ulmart.ru/computers_notebooks/?r=1__75076;1__90522;1__90591;1__89105;4__1160_7170

I need the signal to either have a range of 130-140 meters, or to be directed to the same distance.
What stats to look at and how do they affect range?
Can you give some advice based on personal experience?

Answer 1

Take Yagi D-Link ANT24-1201. Will work great. This one provided me with a connection for three years in much worse conditions, hung outside the window, icicles hollowed out on it every spring. It still works. The truth was dismantled recently as unnecessary.
Do not get carried away with amplifiers, firstly, they are not needed at such distances, but you can get serious crap with communication supervision.
Choose better not access points, but routers that can work as a wifi client. Optimally - those for which there are custom firmware, where the power can be tweaked, and in general the functionality can be expanded quite well. In general, I think you will definitely get 50 megabytes of real speed in your conditions.

Answer 2

Drunk said correctly - you need to understand what kind of distance it is.
Two houses - what is the height? Are the trees big?
What will be connected? Two routers or a router and a computer?
If two routers, then directional antennas. Or the attachment-amplifier on the antenna (seen on dealextreme) amplifies up to 500 mA.
To the extreme on the tin can antenna itself (google to help how to make a directional antenna using a tin can)

Answer 3

It is also important here that you want to "take out the window" of the antenna. Cable loss can be commensurate with the advantage of the chosen antenna. And directed in any case is better, because. there will be less interference to reception. And many of them fit perfectly indoors and work at such distances.

Answer 4

Walmart is definitely a worthy store, but wifi antennas are not its specificity.
Here you have a website for a good office, there are any antennas and excellent specialists who will always help, make pigtails, adapters, and so on.

Answer 5

The question requires too many clarifications. Are there any obstacles between the antennas, what kind of obstacles are they, inside or outside the building is all this happening?
Even regular antennas have a range of 130-140 meters, in a relatively open space.
