規格與說明:

The Joymax UBF-V125cc2B-xxxx antenna is an internal/embedded, adhesive-mount, Flexible Print Circuit (FPC) board dipole antenna designed for use in 315 MHz band supporting low-power, short-range application e.g. remote controls, smart sensors as well as other unlicensed application in the 315 MHz frequency range.
  
The FPCB antenna provides an 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
