Testing NanoVNA V2...

This weekend I make some test with NanoVNA V2, testing some filters and antennas. The results are more than very good. The idea is to understand how thw network analyzer works and specialy how is calibrated. Assisted with software (due the small size of screen) I manage to make some profiles to HF amateur bands and also for VHF and UHF helping me later to make my tests. 

Im very exciting with this new toy...!!
