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

Subject: [OFARC] antenna analyzers
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?
