The Joymax GAF-121Bcc3B antennas is a straight whip-style, magnetic-mount, monopole antenna designed for use in Sub-1 GHz 868 MHz and 915 MHz frequency bands supporting low-power, wide-area (LPWA) applications such as LoRaWAN® , Sigfox®, Wi-SUN®, Weightless-P™, and WiFi HaLow™ as well as other unlicensed ISM applications in the 868 MHz and 915 MHz frequency range.
The antenna has a built-in magnetic base, provides an external remote antenna solution to easily mount on metal plate e.g. vehicle roof. Connection is made to the radio via a RG174 coaxial cable terminated in an SMA plug (male pin) connector.
