How to organize a cheap Wi-Fi bridge for 300 meters?

Question

Computer networks

I wish you all hello, you need to organize a wireless bridge between two networks at a distance of a little less than 300m, there is a direct line of sight, from possible interference there are several 220V power lines and a busy highway. There are practically no other wifi networks in the area.
The question is to choose the cheapest possible equipment, legal aspects and software implementation do not apply to my question.
I am looking at Chinese adapters based on Ralink 3070 in conjunction with a simple directional antenna, but how they all differ is not entirely clear.
Maybe you can suggest another alternative.

Answer 1

Perhaps Ralink is the best wifi chips on the market. This is the only thing I can say :)
Well, in general, only technical data and tests will show the result, the main thing is that everything agrees in theory and on paper.

Answer 2

You take two cheap access points from a long one, I used to take an ap 2100, I think now it’s more advanced, take two cheap directional antennas, set it up. Voila.
In general, the budget will not get out for 10k rubles, or even 6k.

Answer 3

Yes, you can use a pair of Ubiquiti NanoStatiom or Ubiquiti NanoBridge.
