The Joymax GWX-180BSA2B antenna is a whip-style, dipole antenna designed for use in sub-1 GHz 915 MHz supporting low-power, wide-area (LPWA) applications including LoRaWAN®, Sigfox®, Weightless-P™, WiFi HaLow™ and other unlicensed ISM application in the 902 MHz to 928 MHz frequency range.
 
The tilt/swivel design allows the antenna to be positioned for optimum performance and reduces the potential for damage from impact compared to a fixed whip design. The antenna attaches with an SMA plug (male pin) connector.
