About This Product

The Right Angle 900MHz 2dBi Monopole Antenna is a compact quarter-wave antenna designed for 900MHz RF communication and telemetry equipment. Its right-angle construction keeps the antenna closer to the mounting surface, making it useful where a straight antenna would be inconvenient or interfere with the surrounding installation. The antenna uses an RPSMA connector and is designed for compatible RFD900-series radio and telemetry systems. RFDesign specifies a 2.1dBi gain for this antenna.
