There is a task (without large investments) from point A to point B to transmit a WIFI signal. 2 one-story buildings are located on the same straight line but with a difference in height. Within 200 meters. The goal is to get a stable connection. Need a DIY solution so to speak. After walking around foreign search engines, I found a lot of different solutions, including those from our Chinese brothers. There are those who implemented something similar and really working share.

1. The router should be more ceiling
2. Directional antennas
Both are bought in stores. If the connection is point-to-point, then this is called a "radio bridge".

Bank antenna , she is also a cantenna or "can antenna".
implementation examples for WiFi
Very cheap and cheerful, there are a lot of calculators for calculating, and for 200 meters you can even assemble it "by eye".
Another option is a biquad

There is a line of sight - there is WiFi, there is no line of sight, there is no WiFi. That's all.
What is not very direct visibility is difficult to imagine. A little curve? Need to look straight ahead and then right?

2 one-story buildings are located on the same straight line but with a difference in height.

How does height affect this? Need to know if there is a line of sight.
Can you see point B from point A?

Regular Wifi router for 1000 rubles. transfers to a laptop between houses 100 meters from the 5th to the 4th floor. Both devices are in a room behind glazed balconies. The router is on the windowsill in the room.

Two Mikrotik SXT Lite 2 will cost less than a collective farm with banks and RF cables. You can also search for them.
