Editorial narrative

This is a magnetic base omnidirectional antenna tuned for operation in the license-free spectrum band of 433 MHz, 470 - 510 MHz, and 860 - 930 MHz. It is lightweight and can be easily mounted on a metallic surface thanks to its strong magnetic base. We designed this antenna to be a perfect match for RAK7258 , with stable performance and good VSWR. The coaxial cable attached to the magnetic base has a length of 1.5 meters.
