摘要
中波广播频率范围是526.5~1606.5 kHz,频道间隔是9kHz,一共有120个频道。卫星天线作为收、发机的前端和终端设备,除了在设计方面会对无线通信质量产生影响以外,安装是否正确与无线通信质量的好坏也有着最直接的关系。简要阐述中波转播台卫星接收天线的安装与调试要点,旨在为卫星接收天线安装与调试工作提供参考。
The medium wave broadcast frequency range is 526.5~1606.5kHz. The channel spacing is 9 kHz. There are a total of 120 channels. Satellite antennas serve as the front-end and terminal equipment for transceivers. In addition to the impact on the quality of wireless communication in terms of design, whether the installation is correct or not has the most direct relationship with the quality of wireless communication. This article will briefly explain the installation and debugging points of the satellite receiving antenna of the Zhongbo relay station, aiming to provide reference for the installation and debugging of the satellite receiving antenna.
