This simple spring antenna matches great with any of our 433Mhz, 868Mhz and 915Mhz Radio Modules and LoRa breakout boards. They're made of copper-clad wire so you can solder them easily.
They are compact, only 10mm to 18mm long, and have 1.5dBi of gain and 50Ω impedance, so it will work fantastically with just about any 433, 850~950MHz wireless receiver/transmitter.
So far, all the products that we have purchased from Think Robotics have been accurate. Only in the last order, we faced a small issue where the product accuracy was slightly lower, but this was resolved with the help of Think Robotics staff. Overall, everything is satisfactory, and we would recommend everyone to prefer Think Robotics products.
