400 Meters Full Duplex Link Advice

I would like to setup a 400 meters full duplex link with Mikrotik.

2x Mikrotik RouterBOARD 433AH
2x Pointyng Dual 5Ghz Dual Polarization antenna enclosure
4x Routerboard card R52Hn

I’m trying to achieve 80+ Mbps link full duplex (perfect line of sight). Does the routerboard, minipci card and antenna enclousure make senses?

Thanks for any advice.
