摘要
为保证中波发射对特定区域的覆盖效果,多采用定向天线达成目标,本项目对特定频点发射天线采用了单塔斜拉线弱定向技术以增强对主方向的覆盖。经历计算机仿真计算、模型试验验证和安装实施过程,最后经过对覆盖区域场强的实测,达到了设计指标,实现了所需的功能,保证了覆盖效果满足使用需求。
To ensure the coverage effect of medium-wave emission on specific areas,directional antennas are usually used to achieve targets.This project adopts single tower diagonal cable weak directional technology for specific frequency point transmission antennas to enhance coverage in the main direction.Through computer simulation,model testing,verification,and installation,the desired coverage strength in the measured coverage area has been achieved.This approach meets the design criteria,fulfills the necessary functionalities,and ensures the coverage effect of usage demands.
