The MiniVNA is a tiny antenna analyser working from 0.1 to 180Mhz. It is connected to the computer with just one USB cable with power being supplied over the USB port.
The MiniVNA allows you to quickly analyse any antenna within the 0.1 to 180MHz range and view all parameters in real time. You can see at a glance where the antenna is resonant, what the SWR is and what the return loss is. The best (minimal) SWR frequency is automatically found and displayed.
Two markers can be freely placed within the shown frequency range and measure impedance [Z], resistance [R], phase [ω] as well as and values at these points.
Other functions of the MiniVNA allow you to measure cable losses, cable length, transmission, bandwidth and quality of filters and traps etc.
