See the four resonant points of multi-band fan dipole antenna on NanoVNA! They are for 40, 20, 15 and 10m amateur radio bands. The antenna has elements only

Checking SWR of CP22E antenna with NanoVNA on VHF and UHF, to see how the VHF antenna works on UHF as third harmonic. That is because I have

I have been trying to figure out SWR measurement with the new NanoVNA! Here it is, SWR measurement of my half wave dipole 80m antenna.

It is always nice to have verification of calibration on NanoVNA. Method of verifying calibration is detailed here. From the menu, select display and activate the Smith chart

Have a look at my new Arduino Nano! I have been hearing about it for the past 2 years as the microcontroller in uBITX radio. This closeup picture

You need a MicroSD Card in NanoVNA to store and recall information. Without the card saving information is not possible.

There are a couple of LEDs, a USB port, on/off switch and multifunction switch on the top panel of NanoVNA. Let us familiarize ourselves with the function of

There are several traces on the NanoVNA, cluttering the screen. Let us see how we can activate each one and also how to make each one disappear.

Setting frequency range and calibration of NanoVNA has to be done each time you change the frequency range. If you have inserted an SD card in the device,

I need an SMA male to SO239 patch cable for using NanoVNA as my antennas terminate in PL259 connectors. Calibration is done using a PL259 Calibration Kit for
