Connector type help need

Hello

I have Mikrotik Wap LTE and want to extend WiFi signal with external antennas, but unable to discovery connector type onboard.
It looks like MMCX but female, and what type of connector can be plugged in?

I’d attached photos of those 2 connectors.

Any help would be appreciate.

Thats a test-point for wireless calibration during manufacturing, not an connector to external antennas.

To use another antenna, the signal path must be cut before entering the built in antenna. This of course is very risky and voids warranty.
