I love my NanoVNA. I used it to tune my 6 band fan dipole. That took a lot of tuning! It works fantastically, and I've made contacts from the UK to Australia with it.

I've also used it for measuring the resonance frequency of tuned circuits and even as an RF signal generator.

Every radio amateur should have one! In fact if you are into any sort of radio it is useful. I also used mine to investigate the quality of various WiFi antennas to see if they were resonant in the right places.
