WitrynaFortunately, the NanoVNA can be used to measure port isolation! And the NanoVNA can withstand up to +20dBm input, so you can calculate if a given setup for some frequency range is going to work once you measure the switch. AH6BI • 1 yr. ago I coincidentally just watched this yesterday... WitrynaNanoVNA SWR plot of the MFJ-1984MP end fed half wave 40-10meter antenna across all frequencies from 6mhz to 40mhz. It takes a bit more fiddling and understanding of the NanoVNA itself to use it but if you are willing to do that, it's a powerful, inexpensive antenna analyzer alone. I'm guessing that is how most of us will use it.
