浅谈机械式天线升降桅杆

On the Mechanical Lift Mast Antenna

由于受地球曲率和地面障碍物影响,通讯、雷达设备工作时微波天线必须架高才能保证接收信号强度,而在非工作状态,为了便于储藏与运输,需要把天线收回。因此,通讯、雷达设备需要一套升降装置来承担天线架设和撤收任务。本文介绍了机械式天线升降桅杆的概述与分类、几种典型结构桅杆特点与用途和桅杆安装架设注意事项。

Due to the curvature of the earth surface and obstructions , communications device operation of the microwave radar antenna must be elevated in order to ensure the strength of the received signal , while in the inoperative state , in order to facilitate storage and transport , the antenna needs to be recovered . Thus , communications and radar equipment need a lifting device to undertake antenna erection and dismantling tasks . This article describes the mechanical lift mast antenna overview and classification , several typical structural characteristics of the mast and the precautions during mast installation and setting up .
