Mikrotik with 2 or 4 AP

Hi to all :wink:

I need to create private intranet with wireless solution. Wireless will be setup on river Iron gate.
The left side of Iron gate is 40 meters deeper then the right side, and iron gate is 50m long.
I need to cover 1km up and down from Iron Gate with wireless signal.
So my question is: do i need one mikrotik 433AH with 2 or 3 wireless card for AP or
one 433AH and another 2 or 3 mikrotik in AP mode ?
Can both solution create WDS ? or is some another solution

For AP antenna i will buy : Sector antenna – Hyperlink 17db 120’

Sorry for all this newbie questions, this is completely new for me.
Thanks

The more wireless cards you put in the more power you will draw. If it were me I would break it up to keep from a problem taking everything out.

Hi j2wi,
Thanks for reply, so if I understand you.. u think is better to buy one RB 433AH for main router
and WLAN, and another 3 or 4 Router board and to configure them like AP ?
If I go with this solution, what Router board to buy for AP ?

Thanks
