100+ kilometers? wow, that's a long distance~
Although we can establish the connection at the end, the speed will get very slow.
it's not a good method~

It will be 20km between every two stops. However, it's still too long. Even if we use TL-WA7210N with TL-ANT2424B, I think 10 stops is needed and we need professionals for the installation.

Every two antennas must strictly aim to each other and be aligned in the same line without any obstacles between them. (Like a vast plain or Two skyscraper)
Otherwise the signal and speed will be frustrating. Better perform a field-test first between two stops.
