The solution you need is called 'wireless ethernet'. Liie this one: https://www.amazon.de/dp/B08P4LNZML/ref=mp_s_a_1_16?crid=20DX1D7ZK5Y9Y&keywords=mikrotik+g60+cube&qid=1641170552&sprefix=mikrotik+g60+cube%2Caps%2C147&sr=8-16
This SKU contains 2 devices that are paired in the factory. One is labelled master and the other is slave. The slave goes in your farthest site.
Now here the important stuff: there is nothing to configure. You mount them outside, hook em up and your done.
One caveat for this model : the ethernet jacks going in the devices need to be crimped by hand, as the coverplate that insulates the cable from rain was designed too small. A 'machined' cable is too unflexible just behind the jack .. to both be plugged in as well as 'covered' by the plate. Other than that its recommended.
Use a pair of mikrotik 60G ac. https://www.amazon.de/MikroTik-preconfigured-CubeG-5ac60ad-W125911911-International/dp/B08P4LNZML/ref=mp_s_a_1_27?crid=2FFDI01J49B2V&keywords=mikrotik+60g+ac&qid=1636587407&sprefix=mikrotik+60g+ac%2Caps%2C130&sr=8-27 They are paired in the factory, you only need to plugin power and ethernet cable
At that distance, if size is an issue, they also have a smaller version, the Cube: https://www.amazon.com/MikroTik-Wireless-Wire-Cube/dp/B08P4LNZML/
