規格與說明:

The Joymax GWX-180ASA2B antenna is a whip-style dipole antenna for sub-1 GHz 915 MHz and low-power, wide-area (LPWA) applications including LoRaWAN®, Sigfox®, Weightless-P, WiFi HaLow and other unlicensed ISM bands in the 902 MHz to 928 MHz 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) or RP-SMA Plug (female socket) connector.
