The Joymax UHX-328Acc2B is a straight whip-style, monopole antenna designed for use in 315 MHz band supporting low-power, short-range application e.g. remote controls, smart sensors as well as other ISM unlicensed band application in the 315 MHz frequency range.
The antenna features IP65 rated waterproof design and omnidirectional radiation, ideal for small IoT and portable products. Connection is made to the radio via a SMA plug (male pin) or RP-SMA plug (female socket) connector.
