The Joymax GRF-V090MP3B antenna is an adhesive-mount, rigid PCB (Print Circuit Board), dipole antenna designed for use in Sub-1 GHz 868 MHz and 915 MHz bands supporting low-power, wide-area (LPWA) applications including LoRaWAN®, Sigfox®, Weightless-P™, WiFi HaLow™, Remote Control and other unlicensed ISM application in the 868 MHz and 915 MHz range.
The antenna provides a ground plane independent internal/embedded antenna solution to easily mount in RF transparent (e.g. plastic) enclosures, enabling environmental sealing and for protection from antenna damage. Connection is made to the radio via a coaxial cable terminated in an MHF plug connector
