Not being an electronics professional but face the following problem I hope you can help me.
I would like to estimate the losses due to an impedance mismatch of connector used in wall-crossing of a coaxial transmission line.

Unfortunately, I do not have the experimental resources for testing the connector (with network analyzer).

Is it possible with analytical formula or with simulations?
