MIKROTIK ROUTERBOARD RB/922UAGS-5HPACT-NM

Hi Guys,
To get a better 4G (LTE) connection, at the holiday house in the mountains, I am looking for a suitable router.
In another thread in this forum (http://forum.mikrotik.com/t/recommend-hardware-for-internal-4g-lte/85512/1) I became aware of the RB922UAGS-5HPacD. In a German shop I found the “MIKROTIK ROUTERBOARD RB / 922UAGS-5HPACT-NM”, which would be suitable for outdoor use.

Can I use this router for my applications? (3G / 4G in Portugal)
Can I connect an external antenna for 3G / 4G? (2X2 or 3X3 MIMO?)

greetings
Daniel

Can not anyone give me an answer to the questions?

You can use this device, but it does not include the modem. You must find a miniPCI-e module separately. The modules usually have uFl connectors for extrernal antennas. The NetMetal device only has a free slot, and a SIM card slot, but modem itself is not included. Buy a modem that is compatible with your provider.
