It realy works!

Portable vector impedance analyzer is a device that allows you to easily examine the basic parameters of antennas. In addition to the low price, it has several advantages. It is small and handy, fits in a pocket or a bag. It has a built-in battery that can be charged from USB. But above all, it really does a good job.

Wide range of work frequencies (from 137.5 MHz to 2.7 GHz) allows you to study almost every antenna in your workshop. In this range you will find: 310 MHz from garage doors; 434 MHz from popular remotes; 868 MHz for LoRa; 915 MHz ISM; up to 2.4 GHz for WiFi, Bluetooth, NRF24L01+ and many other devices. Only the 5 GHz WiFi band is out of range, but it would be simply not fair to expect it from such a cheap device.

Making long story short: in this price range it is an absolute remarkable device. For us, the best recommendation is the video published by our favorite “Youtuber with a Swiss accent”.
