This simple spring antenna matches great with any of our 900MHz RFM and LoRa breakouts, bonnets and Feathers. They're made of copper-clad wire so you can solder them easily. They are compact, only 17.5mm/0.68" long, and have 2.15dBi of gain and 50Ω impedance, so it will work fantastically with just about any 850~950MHz wireless receiver/transmitter.
