Any suggestion for the matching circuit at the output (or input) for the NanoVNA measurement ? Which L/C components to choose ?

I like the idea for matching by using adjustable L/C components manually or electronically (see e.g. PE64102B-Z, 1.88-14pF, SPI).

I am sorry I do not understand. Can you be more specific? What else should be included?

I said neutral "If indeed it is so, then let be happy my friend". And nothing more.
