The nano vna 4” is the way to go.  Calibration is easy.  These do everything, return loss, TDR, smith charts.

I have seen some very nice antenna analyzers from Comet and RigExpert.  They cost anywhere from $200 to $600 depending on the model.

I have used some of them and they do a good job.  Apparently they are ready to use out of the package…no calibration routine needed.

 

Then there are small units called VNAs that cost $50 to $200.  They seem impressive for the small size and do everything the big ones do.  It appears some of them require a special calibration kit and need to be checked every time they are turned on.

 

I want an analyzer for building antennas from HF through UHF.  A bonus would be a function to check band pass filters (some VNAs seem to include this function).

What is your experience and recommendations on the options?
