Dear friends,


I have a question, when installing 4T4R RRU and connecting it to Antenna, the RRU has 4 ports (A,C,D,B) and Quad Antenna has (5+,6-,7+,8-).
Does the connection matters? in other words, Is it same if we connect like this:
A--->5+
B--->6-
C--->7+
D--->8-

Or
A--->5+
C--->6-
D--->7+
B--->8-

And what is the effect.
