I set up the device to sweep from 130MHz through 460MHz. Here is a screenshot of the measurement of my antenna: With the nano-VNA and the PC software this was very easy. Once I put it together I needed to tune it for a low SWR in the two bands. I used this device to tune a little vertical dipole I was building for 2m and 70cm (I will write a post about this one later). You can download the latest version for free here: There is a great comanion program called the nano-VNA Saver. The best way to use this little gem for antenna testing and tuning is by connecting it to your PC. The nano-VNA does these perfectly and does so from 50kHz to 900MHz, some versions even from 10kHz to 1.5GHz.īefore the first use, you should calibrate it but all the necessary adapters are included and the calibration is very easy. I have no experience using a vector network analyzer but the functionality I am interested in as a ham building an antenna, is the standing wave ratio curve and the impedance measurements. It is called the nano-VNA, a vector network analyzer in a very small and compact form factor.
