Environmental Factors Affecting UAV Onboard Antenna Communication Effect

Unmanned aerial vehicles work in complex outdoor scenes with variable altitude, high-speed vibration and mixed outdoor electromagnetic signals, which raises stricter durability standards for flight control and data transmission antennas. Sudden signal disconnection during long-distance flight is mostly caused by insufficient antenna gain or poor anti-interference design.Continuous motor vibration easily loosens antenna welding points, so fixed structural reinforcement is essential during antenna installation. Dustproof and waterproof outer packaging further improves environmental adaptability for field-used UAV antennas.
