SP’23 Foxhunt + Yagi Antenna Build

On May 6th, we held our first foxhunt-adjacent event at the local makerspace on campus–EnVision. Big shout out to them for letting us borrow their workspace for our event. We are still in the process of getting a space for the club itself. We didn’t get to much foxhunting because the yagi antenna build took longer than expected since most of us haven’t built one before. We did, however, test it a bit from the nearby parking garage.

It was a cool learning experience to see from the NanoVNA antenna analyzer brought by one of our members how the Yagi Antenna was optimized for directional (as seen by the peaks in the photo–the antenna only had a sharp peak at 2 frequencies). We also started to build our transmitter from a relay, Arduino and Baofeng radio (referencing this video on foxhunt transmitters).

Thanks to all those who showed up! We hope to host more events like this in the future–perhaps with more hunting involved.
