Significance of "Antenna Mode" in 'N' working radio?

RouterOS Wireless Networking
1

Can anybody tell me?
I have rb433AH on both end running with ´N´ link and duo Pol antenna

I just upgrade ros 4.10 to 4.16 and put NV2 wireless package enabled.
Now I see a “Antenna Mode” setting. I tought the ot chains were already representing the two antenna connectors?
What is now this option? I swap between Antenna A and B but apart from that the radio’s temporarily disconnects nothing changes…?

please ignore this setting, it was added there by accident - this will be fixed in the next release of the RouterOS.
