After connecting the ML-2452-APA2-02 antenna to AP460e, the parameters are shown at the below image, it seem the AP460e does not recognize the ML-2452-APA2-02 antenna, isn't it? And the current Tx power for 5G is very low (11dbm) , while the 2.4G radio is 22 dBm.
Does anyone let me know the configuration is true or not ?
But at the article you send, the ML-2452-APA2-02 is available, and i do not see the ML-2452-HPA6-01 which is available in the Antenna Compatibility Matrix ?
Per the Antenna Compatibility Matrix, this antenna is not compatible; however, have you tried configuring the antenna id and group per this article? https://extremeportal.force.com/ExtrArticleDetail?an=000100518
