[Battlemesh] Custom Dual AP antenna setup for one router antenna plug

[cmsv]

Hello Bastian.

The idea to do this is quite similar to one of the described cases bellow.
I have this church tower right in the middle of my mesh. It is  a
perfect spot for an access point. However to make it a directional node
it is impossible to reach the top. The other option is to use the towers
windows (4).
This would mean 4 routers and 4 directional antennas but i can deal with
only 2. The point is a direct link to my gateway node from the west side
and then send the link out through the east side and in other to avoid 2
routers; i would use only one with 2 biquad antennas.

However the majority seems to claim loss of performance. Can you confirm?

According to this:

There is a 5.1 dbi loss.
