EU1KY Antenna Analyzer Kit

Recently, my local amateur radio club has been developing a DIY antenna analyzer (AA) based off the Jack Purdum (W8TEE) antenna analyzer that was featured in the November 2017 issue of QST. Based around an Arduino Mega 2560, the current design and specifications that my local club is attempting to expand the range from 1-30 MHz, of the W8TEE analyzer, to 0.1 - 500 MHz approximately. The goal is to cover not only HF, but VHF and UHF as well. It is quite ambitious given that we are trying to aim for around $150 price point and trying to get roughly the same, if not better, performance that the W8TEE analyzer.

This project has been ongoing since January of this year, and there have been typical engineering struggles and challenges (i.e. Fighting with CAD tools, Sourcing an inexpensive oscillator for this application, etc). Even though I bought into the project, I honestly got pretty impatient, so I started to look on my own at other DIY Antenna Analyzers that exist. Some Googling led me t…
