Serving Since 2003      

The most affordable vector HF antenna analyzer in the world! USB connection & free software. Arduino users: add a vector impedance analyzer and an RF generator to your project!

Why the AA-30.ZERO?

Creating the AA-30.ZERO, we met the numerous wishes of radio amateurs and DIY-hobbyists to give them a measuring tool that can be easily integrated into their own projects. The analyzer is available as a kit to meet this requirement.

Ready for use

The analyzer has everything necessary on board: users can connect the AA-30.ZERO to their PC (through a USB to UART-TTL adaptor) and perform all usual sets of laboratory measurements, just in five minutes. The AA-30.ZERO is perfectly compatible works our AntScope software.


Experienced users may pair the AA-30.ZERO with Arduino boards making their own hardware/software project, since the AA-30.ZERO is compatible with Arduino standards. Also, we have made available several examples of running the AA-30.ZERO in DIY projects.

More ideas:

Want to make your own automatic antenna tuner ? Use the AA-30.ZERO as a replacement for the directional coupler!
Want to perform RF-circuits or antenna analysis remotely ? Pair the AA-30.ZERO with the ESP8266 Wi-Fi SoM and do it easily!
Want to tune your antenna with driven elements? Use the AA-30.ZERO for fine tuning.

price & POWER

There is no chance to find such powerful competitor analyzer for such a low price. With the AA-30.ZERO, dreams of radio amateurs are coming true!
