There has been discussion about calibrating at the transmitter end of the

It might be interesting to see the Smith Chart and SWR plot right at the
antenna terminals. I have two HF antennas with easy access to the ends of the
coax cables. A different set of calibration standards or adapters may be
required.

On several occasions I have done the calibration at the end of the transmission line where it connects to the antenna. It works very well but requires a lot of running back and forth between the antenna and the ham shack.
hence the switch box <grin>? - It's having an Ecal unit out there.
