nanoVNA

I just couldn't resist.

 Ordered a nanoVNA that arrived yesterday.

I was able to do my first antenna analysis after looking at some youtube movies.

Here you can see a homebrewed 2 m antenna under test. A nice dip exactly on 144 MHz in the attenuation trace. The Smith chart shows almost a 50 ohms impedance (the green triangle near the centre).

 It is an impressive toy for a few bucks (aliexpress, amazon). It enables you to analyse antennas, filters etc. from 50 kHz - 900 MHz !

    Ik kan je de nanoVNA van harte aanbevelen Hans. Voor rond de 25 euro heb je er al een. Ik zag dat er ook duurdere versies bestaan, v2 en f geloof ik.
