Doing it Live - Mikrotik Chateau 5G ax - Adding SMA connectors for external LTE/5G antennas

Drilling holes in a $600 router to add SMA connectors.
This will allow me to move from the internal antennas in the device to external antennas mounted on the outside of the building at the install location.
Why? Because the building at the install location is all metal. Making for a weak signal inside.
