摘要
电视发射天线是电视信号传输中的重要设备,天线工作状态的好坏决定着发射效果,因此,本文根据2016年平阳水头蒲尖山无线地面数字覆盖工程建设中遇到的问题,简要介绍分米波发射天线天馈系统方案选择及路测场强覆盖。
A TV transmitting antenna is an important equipment in television signal transmission, Whether good or bad the antenna operation depends on the status of the antenna effect. So, according to the problems that happened in DTTV wireless digital coverage engineering in Pujian mountain of Shuitou of Pingyang in 2016, the paper briefly introduces the decimeter wave transmitting antenna feed system scheme selection and road test of field strength coverage.
