External antenna for MikroTik mAP 2nD

The router is placed in a metal box and I cannot mount it outside

Can I connect external antenna for MikroTik mAP 2nD (I want to mount the antenna outside the metal box)?

What type of connector is in the picture?

This is not a connector, it is a switch MS-156C, used in manufacturing to connect instruments to adjust the device.

There is an adapter for the SMA

The very idea of putting a homemade antenna system is a very bad idea.
By unsoldering the switch you have disconnected the internal antenna.

Thanks for correcting me ca6ko! Looks like I shouldnt assume something by just looking at it.
However, why would connecting to it an external antenna be such a bad idea?
If you connect the external antenna by a proper connector, the switch disconnects the internal antenna.
As long as you have a proper external antenna, connected well, nothing can go wrong.

The main issue I see here, that the “SMA Conversion Adapter” which you could use to connect to this connector properly,
would probably cost you more than anyone would like to spend on such a setup!

The alternative way, soldering around 5GHz transmission lines by hand would for sure not be a good idea.

Sorry for bringing up an old thread, but wouldn’t such an adapter be okay?

Yes and no.
Yes It will work.
No that Is not intended for permanent connection, It Is a kind of probe, for temporary connection and It Is too long to be practical.

But this should do:
