I had the parts on hand so I built a quarter-wave antenna for my FOSS TinyGS (satellite ground station).
I deployed the antenna on a post in the backyard, now to see how well it performs. The SWR and Smith charts look very good but real world performance has a mind of its own.
I also used parts on hand to build a battery+solar panel charger for the TinyGS. It tested out OK but for now the actual Lora board is powered from mains.
