要进一步扩大广播电视的普及率,除了进一步发展电视接收机的生产、销售之外,还必须加快在偏僻的山区、农村兴建小型电视差转台的工作。从某种意义上讲,兴建电视差转台与发展电视机生产具有同等的意义。为了适应兴建小型电视差转台的需要,本文就适用于山区、农村的简易电视差转天线的设计作一介绍。一、对差转天线的基本要求兴建电视差转台,首先要考虑差转天线的质量、形式、架设等,提高差转质量。就电视差转天线的应用而
To further expand the penetration rate of radio and television, apart from further developing the production and sales of television receivers, it is also necessary to speed up the construction of small-scale TV repeaters in remote mountainous areas and rural areas. In a sense, the construction of a TV station has the same meaning as the development of TV production. In order to meet the needs of building a small TV repeater, this paper introduces the design of simple TV antenna for the poor TV in mountainous areas and rural areas. First, the basic requirements of the poor turn the antenna To build a poor turn table, we must first consider the quality of the antenna to change, form, erection, etc., to improve the quality of the poor transfer. On the television transfer antenna applications
