Hello!
We have had this situation 2 years ago, and we have solved by buildine AP using:
1. Mirkotik board with 5 GHz ac integrated card https://mikrotik.com/product/RB922UAGS-5HPacD
2. make the AP dual band per each board we installed https://mikrotik.com/product/R11e-2HPnD
3. For housing outdoor we used station box s https://rfelements.com/products/integration-platforms/stationbox-s-carrier-class/stationbox-s-carrier-class/
4. For housing indoor we used https://rfelements.com/products/integration-platforms/stationbox-inspot/stationbox-inspot/
5. for outdoor AP we used those antenna https://rfelements.com/assets/Uploads/Datasheet-Antenna-Omni-24G4dbi.pdf and https://rfelements.com/assets/Uploads/Datasheet-Antenna-Omni-5G5dbi.pdf
6. for indoor AP we used those antennas: https://rfelements.com/assets/Uploads/Datasheet-Antenna-Omni-245G23dbi.pdf
7. in all cases the pigtails are needed.
