I would probably test a parallel tuned trap as a single port, with the far end of the trap grounded.
Should see the impedance head towards zero at the resonant frequency.
But could also be done as a 2 port measurement, loss approaching zero at the resonant frequency.
You will find that the resonant frequency will change when the trap is part of an antenna.
So do a single port test of the completed antenna, that's the real test.
Could be displayed as impedance, SWR, Smith Chart, whatever you are comfortable with.
Look at each band individually, sweeping all of HF may not give enough resolution to see resonances.

Hello all...
I'm new to VNA's, and need some guidance.
What is the way to connect my NanoVNA-H to a dipole antenna trap so I can tune
it, and read resonant frequency, Q, impedance, etc.?
Thank you for your time.
Ed
