About This Product

The 900MHz 2dBi Monopole Antenna is a compact quarter-wave antenna designed for 900MHz wireless communication and telemetry systems. Its lightweight construction makes it suitable for UAV and FPV applications where antenna size and weight are important. For proper RF performance, the antenna should be installed with a suitable ground plane. The antenna uses an RPSMA connector and provides vertical polarization for compatible RF systems.
