Choosing a Wi-fi Antenna

Question

WiFi

Good day, there is a technical requirement: to provide a remote object with the Internet at a distance of up to 1 km, visibility is direct, but you may have to move it and the route will not have direct visibility (trees). Budget 1000 hryvnia. There will be two TP-Link WA-701ND access points in the bridge, I can’t decide on antennas. Reading the expanses of Google came across the following:
- Bikvadrat ;
- Spiral ;
- Sector ;
- well, a very simple can ;
- well, like this .
Advise which antenna is most suitable for such conditions and what will be the approximate bandwidth of the channel?

Answer 1

“Well, a very simple can;” - in no case
"Spiral;" - it will also be rather weak, and also strongly depends on the build quality of
"Bikvadrat;" - only if it is in the focus of a parabolic dish
"so and so." - antennas such as a wave channel may be suitable, you just need to choose by gain and radiation pattern and try.
And a normal (tested with us) would be a segment-parabolic antenna with a grating reflector, such as
Antennas for 24dBi - enough for three kilometers and a speed of about 18 Mbit
Well, of course, parabolic antennas and emitters at 2.4 GHz are suitable
