For everyone that wants to do complex transmission line analysis and has access to a sufficiently new MSOffice suite I suggest they use ZPlot, a free tool written in Excel
It can be downloaded from here
The excel file contains the calculation models for complex transmission line measurement calculation and compensation using a k0,k1,k2 model.
Using nanoVNA saver you can measure your antenna feedline with the antenna disconnected and replaced with a OPEN/SHORT
The resulting two touchstone files can be imported into ZPlot and ZPlot will calculate a full transmission line model (k0,k1,k2) for your antenna feed cable including the delay.
Then you measure your antenna connected to the feedline and import in ZPlot using the calculated transmission line model and have all the details of your antenna without the impact of the cable or you use the calculated delay in nanoVNA saver to quickly eliminate the biggest impact of the feedline
