HamRadio 360 Workbench – Antenna Analyzer

August 6, 2016


Welcome to the HamRadio 360 Workbench Antenna Analyzer project page !

This is a quick glimpse at our first Workbench community build project.  This antenna analyzer was designed by our good friend Beric, K6BEZ.  The idea is to make a low cost antenna analyzer that can be battery operated and used in the field or plugged into a PC to extend it’s functionality.  This picture is the rev 1 prototype board which was designed in Cadsoft’s Eagle PCB design tool.


This is a partially build board.  The upper left solder pads are for the right angle BNC connector.  The blue daughter board on the top left is the DDS (direct digital synthesis) board which generates the signal.  The little blue board to it’s right is an Arduino Pro Micro which has a micro USB jack.  To the right of that is the DC power input jack.  The big dark rectangle is the 2 line x 16 character LCD display and there are three push buttons to the right.

The final version of the board will look pretty much like this. The whole design including the hardware schematics, layout, firmware and optional PC software will all be open source.

Stay tuned to the HamRadio 360 Workbench podcast for more details.

    this is great stuff and hopefully a case will be figured out. many hams can use this prjevt as a way yo get into arduino

      Hi John,
      Yes! I really like this project for several reasons. It’s a handy piece of test equipment to have in the shack at a low cost. The other big benefit is that it introduces the Arduino as a platform for building a project. My hope is that this will inspire more people to build ham projects with these handy microcontrollers. There is also the option of talking to the Arduino from a PC over a USB/serial port so you can write or modify code on the PC side as well.

    What will the specs be for this project? Will they be published soon?

      Hi John,
      All of the details will be announced on the Ham Radio 360 Workbench podcast. We will publish all hardware and software files as open source and we are in the process of sorting out how to make parts kits available. Stay tuned for more details over the next month or so.

    This is a nice little project, and a great way to learn about the Arduino. There is an active Yahoo group dealing with the original K6BEZ and modified designs, and a couple of boards that were made by third parties. I have built several stand alone versions with a graphical display instead of the 2 line display. They worked quite well, for such a simple instrument. With some modifications I turned one into a simple Scalar Network Analyzer.
