Chateau LTE12 setup to use external lte antenna

newbie question here (first time experience with mikrotik)

i got the Chateau LTE12 recently, works nice. I decided to buy after a few days the MikroTik MTAO-LTE-5D-SQ mANT LTE antenna.

Problem is that i cannot find the option to make the Chateau to use the external antenna.

Under the lte option where i should have the option for external antenna, there is nothing on my mikrotik. I am running the 7.1beta6 fw (factoty version was .1beta5)

Any help?

This is a bug apparently. You can set antenna in Quickset too.

Chateau LTE12 factory and ONLY supported versions are 7.0beta6 or 7.0.2 or 7.0.3 as MikroTik staff says.
If you see 7.1betaX something as put wrong beta firmware for that device.

USE SEARCH FUNCTION FIRST instead of open useless duplicate topic
