the nanoVNA has to first produce the signal to see it reflected back...can
you verify with a receiver that it's outputting a signal ? You can set the
stimulus center frequency to whatever is convenient and set the span to 0
and it'll put out a signal at that frequency that you can pick up on a
nearby receiver.Might need to connect a piece of wire to CH0 to act as an
antenna.
Does it calibrate properly with the open/short/load standards? If it does,
that would indicate that it's both generating and receiving a signal.

Yesterday I went to check the resonance of my EFHW antenna with the
nanovna h and found that in no port I can read the signal.
I removed it from the antenna and tested it with a simple dipole and it
also does not present a signal reading in the swr and logmag formats.
I believe the nanovna has a defective input component, as it connects and
I can access all functions.
Does anyone have any solution of what may be happening.
