I built a copy of the MIT/LL coffee can radar last year, but I’m just now getting serious about documenting my results. The coffee can antennas work fine if you build them exactly as described in the course notes, but I wanted to explore a bit more. Although I do have an antenna analyzer, it’s only for the lower ham bands and won’t help me tune up a 2.4 GHz antenna, so I built a simple reflectometer to look at the reflected power coming from the coffee can antennas. Here’s the video.
