In anticipation of the summer season, I was solving the problem with a stable Internet connection within a limited budget.
Given
Lack of mobile operator base stations in line of sight.
Unstable mobile Internet at speeds up to 2Mbps.
Distance to the tower ~ 2 km.
A panel house inside which a Wi-Fi router will be located.
Expect to receive
The speed is not lower than 15Mbps - this will be enough for parallel playback of a video stream in 720p quality on 3 devices.
Coverage of 6 acres with a stable Wi-Fi signal.
Minimum financial and time costs.

Time-consuming: all that had to be done was to connect the devices together, attach them to the wall in the right place and plug them into a power outlet.
Addition
Antenna internal structure:
An important point: using a 4G modem inside the antenna can lead to failure of the modem when operating the solution at subzero temperatures.
