An FPV (First-Person View) antenna plays a vital role in FPV systems by enabling the transmission of video and data between a drone and its operator. These antennas come in various forms, including linear types like dipole antennas and circular polarized options such as cloverleaf and pagoda designs. They can also be classified based on their radiation patterns, offering either omnidirectional coverage for a full 360 degrees or directional signals that focus on a specific area. Important specifications to consider include frequency—commonly at 5.8GHz—gain measured in dBi, polarization options like right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP), and the type of connector used.
