W4RT Electronics MINIVNA

The miniVNA is a full-featured, yet tiny antenna analyser covering 0.1 to 180 MHz. It is connected to a computer with just one USB cable, power is supplied over USB. An internal setting for serial (RS-232) communications is available as well.

The miniVNA allows you to quickly analyze any antenna over a user defined frequency range between 0.1 and 180 MHz. In real time, you can see at a glance where the antenna is resonant, and the SWR, return loss, impedance, phase, etc. as a function of frequency. The best (minimal) SWR frequency is automatically found and displayed.
