The invention discloses a DVOR (Doppler Vor) omnidirectional range reflective net antenna damping system. A damping support I is arranged between an upper strut and a lower strut of a reflective net bracket, a damping support II is arranged between a reflective net and an antenna orbit, and the two damping supports are high-damping rubber gaskets with built-in gasket lined steel plates. The system is reasonable in design and convenient to install, and is easy to replace when the rubber is aged after installation; the damping support I is arranged between a steel girder and the orbit, so that contact between meshes and the orbit is radically avoided, and the trample problem during overhauling or construction is solved; the damping supports serving as dampers consume energy inside, thus effectively counteracting the influence of wind load on an orbit antenna under severe weather and reducing the vibration frequency and times of the antenna orbit; the antenna orbit is effectively separated from the reflective net steel girder, thus avoiding resonance caused by the same frequency with the reflective net; and the damping support II prolongs the natural vibration period of the structure and reduces the vibration frequency of the structure without influencing the structural strength.
