Based on the rugged transportation conditions of the communications equipment used on vehicle, this article analyses and calculates the anti--vibration capacity of the 1.2meter diameter antenna installed on vehicle. Based on the result, isolation vibration instruments are chosed. And then the stress of the an- tenna structure is checked in more analysis. The result shows that through the anti-vibration designing and analysis of the communication equipment, as well as affective measures taken about the anti-vibration, the reliability of equipment of the vehicle driving under complicated mechanical environment can be guaran- teed.
