This is a threaded, single-port connector with solder termination for both the centre pin and the shield, so it's a permanent install — you solder the cable once and bolt it down.

Mounting and termination — what to expect at the bench
The threaded coupling means you tighten a mating SMA plug onto it with a torque wrench.
