Answer 1

Given the mikrotik tag, I suggest the following options in descending order of importance:
1. mikrotik.com.
2. under the bed.
If you didn’t find it in the first or second place, then no one will help you here.

Answer 2

https://www.ubnt.com/

Answer 3

Here is an access point based on the mikrotik board with IP67 performance - RW-225-OUTA ROUTER shop.mti-group.ru/shop/UID_17.html
Antennas for 2 km - any to your taste. Only they will need 2 pieces - separately for 2.4 and 5 GHz.
Although two separate boxes are cheaper than one. Even taking into account the fact that 3 boxes will also be needed - some kind of switch / router with PoE for power, like MikroTik RB960PGS-PB.
