Hello! Distance 1km both sides 28dbi 5ghz.. N-draft need!

At the moment i have next installation

RB433AH one side
3x minipci cards inside (2x r5h +1xr52)
1xR5h → link 4.5km long 5ghzturbo → antenna svenska 60cm 28dbi dish (distance 3km)
1xr52 → omni 2.4ghz - antenna omni 14dbi
1xr5h → PtP to provider… 50mbps/50mbps shows up at the moment → antenna svenska 60cm 28dbi dish (distance 1km)


From provider side we have
RB411AH
R5H
28dbi svenska dish

LOS offcourse

I have next task at the moment:
upgrade bridge from provider to our server room to achive 100mbps full duplex

At the moment we have 2 more 28dbi svenska dishesh.
Are there any troubles with R52hN cards? I could make next way - one dish in vertical, other in horizontal +1.5 or 2m between them from provider side and

from our point

dish that goes on 4.5km goes almost on the top in H-pol

lower about 2m comes first in V-pol to provider and
lower about 1.5m comes second in H-pol to provider

Angle between 4.5km link and link to provider about 45 degrees.



Or I should add one more box for link to provider for example rb411ah with one card, so no intereference in one with 3 cards in…?




I would be appreciate if someone comments my plan !
