High-stability radar lightning rod

The invention relates to the field of lightning arresters, in particular to a high-stability radar lightning rod which comprises a storage cylinder, a supporting device, a limiting device, a guiding device and a traction device, and a lifting disc is arranged in the storage cylinder in an up-down sliding mode. And a lifting mechanism is arranged below the lifting disc. When the lightning rod needs to be used, the lifting mechanism drives the lifting disc to drive the needle body to extend out of the storage cylinder, the traction device provides traction force at the lower end of the supporting rod in the direction away from the needle body so as to improve the stability of the needle body, and when storage is needed, reverse operation is carried out to enable the supporting rod to be stored in the storage groove. And the needle body is stored in the storage cylinder, so that the needle body can be prevented from being exposed outside for a long time to influence the service life, the influence of the exposed
