You can controll the analyzer as an application for Windows

And with the Anroid application

The setup process is very simple. In arduino nano you need upload a sketch
which controls the analyzer in it specified quartz frequency.
The device is power on by USB. The device is calibrated once without load,
and the second time with a load of 100 ohms. Now it can be used.
And now slides)))
I Measured of all my available antennas:
Chinese tail on 433 mHz.

The bottle antenna 5/8 on 2 meters http://www.diygoodies.org.ua/?p=1780

Antenna from a coaxial cable

Dual-band Yagi Antenna

Dipole for 20 m.

Nonsymmetric dipole http://www.diygoodies.org.ua/?p=1497

Very useful device I think , I advise it to everyone. At that’s  all.
