EU1KY Antenna Analyzer


I have always wanted A good analyzer for HF up to VHF (2m)

In the past I have build many Antenna Analyzers started with:

Antan Analyzer

VK5JST Antenna Analyzer

Toghether with Jarek SP2SWJ we have built the BIGVNA MAX5 & MAX3

Big VNA Max 5

Max 3

Some weeks ago while I was surfing the web for projects I came across the:
Antenna Analyzer designed by EU1KY
The software is branched out and extended with many options by Wolfgang DH1AKF.


This analyzer is based on the:
STM32F746NG Discovery (disco) development board.

The development board is available from Farnell, Mouser, RS-Online etc..

The project is quite easy to build. The only thing you have to build yourself.. if you want to go for the lowest costs is the the frontend PCB.

The specs of the analyzer are amazing, the frequency range runs from 100KHz > 600MHz!!!

You can also look on Ebay, there are lot of listings of these pcb’s even pre-assembled.

In the mean time I made several of these Analyzers with great succes!

    Very nice looking 3D printed enclosure. Is there any chance you would publish the code for the enclosure design or even just the stl files so I could print one for my analyzer?

    Thankyou for the stl files… a beautiful design. What cad system did you use to build the 3d models? scad, freecad or one of the cloud based cads?

    Hi bjorn. Welke ringkern heb je gebruikt voor de analyser volgens eu1yk ?

    • pd5dj says:

      Hi Jean Marie, dit is een kern die ik van een VGA kabel af heb gesloopt 🙂
      Dit was ook aanbevolen destijds in zijn artikel.
      Ik denk dat het materiaal voor al dit soort kernen in kabels hetzelfde zijn, dus bruikbaar hiervoor. 73 Bjorn de PD5DJ

    Hi Bjorn ik was ook opzoek naar de stl files maar staan helaas niet meer thinginverse is het een mogelijk dat mij deze kan door sturen met vriendelijke dank en een glimlach Jan PE1JD
