The analyzer I had did impedance as well as SWR. When I had an antenna analyzer I never had to do a cal. Every time I changed bands I did a calibration.
Put my new nanovna-H4 to work this afternoon tuning up a new MFJ Cobweb. NanoVNA, however, Bob's statement imho is not applicable.Īn: Nanovna vs Antenna Analyzer (You will see that accordingly this takes longer, too.) For a solo Just do the calibration over the entire frequency range and you are done calibrating.īob"This is only true, if you use some external software (like NanoVNA Saver) that overcomes Once done, you save the parameters and recall it each time.

Do the cal fpr just the süpan needed, say 3.5.

The real reason is: The NanoVNA, due to it's very limited internal memory,
