Product overview
The GEPRC Momoda2 4.9G Antenna is an antenna component for FPV video transmitter installations. Its operating band extends from 4.9GHz to 5.3GHz, with a center frequency of 5.1GHz. LHCP and RHCP polarization options provide a configuration choice for the intended installation. The RF specifications comprise 3dbi gain, an axial ratio of ≤3, SWR of ≤1.46, radiation efficiency of 85%, and cross polarization suppression of -25dB. These characteristics define the antenna’s stated RF configuration.
The physical design combines FPC and PCB elements inside an ABS enclosure, with an SMA connector for integration. The antenna measures 170mm in length and weighs 12g, giving installers concrete dimensions and mass to accommodate in their layout. Its combined FPC and PCB architecture is intended to improve signal frequency consistency and reduce transmission power loss. The supplied configuration contains one Momoda 4.9G antenna; the product is an antenna accessory rather than a flight platform or airframe kit.
