AT LEAST USE A PORT EXTENSION!!
a male female adaptor (port saver) ... if worn out just replace the adaptor and NOT the socket in the vna
any sma connector that you use often should have such an extender ... be it the vna or an sdr (funcube dongle, airpsy hf+, whatever)
so ... go any buy "a dozen" and put them on ALL of your sma sockets that you use more then 5 times a year :-)

You may have forgotten that you can put an extension cord of the length you want between the nanaoVNA box and the location where you are going to do the calibration. Even the imperfections of the extension will be compensated by the calibration. I did a test with a 93 ¦¸ cable.
Take advantage of this extension to change the type of connector. Switch to a female BNC socket for example, firmly fixed on a support. SMA are too fragile to be screwed and unscrewed too often.
