The title indicates my need, more than a specific resource I have to offer. I recently bought a nanovna because I wanted something that I can test antennas with that won't fry my low serial number Icom 706llg. Problem for me is finding a tutorial that makes sense to me.

Any suggestions for a reasonable resource for a crash course in antenna theory as it relates to using a vna? Google hasn't exactly been my friend. Thanks for your input.
