Wireless wire - 2 dishes close to each other

Hello,

I have a point from where I need two wireless lines. One is

One is about 280m
One is about 40 meters.

However the lines “only” differ about 45° angle (one is from roof to roof, the other is from roof to ground).

If I use two wireless wire lines the dishes on one point will be very close to each other.
Is that a problem?

Any other suggestions?

Thank you
Daniel
