SXT 6GHz modification for external antenna?

Has anyone tried to disassemble the SXT 6GHz to see how hard would be to modify it, replacing the internal antenna with external antenna connectors?
Is the internal antenna permanently soldered, or connected using pigtails with RF connectors?
I ask specifically about the new 6GHz product, has anyone already made some photos how it looks inside?
Why doesn’t MT offer to sell a a bare 6GHz routerboard (same as inside SXT6 but without antenna and case, so they already have the product)?
