本文介绍几种类型的 VHF 全频道电视接收天线的原理,结构和某些电特性的测试与计算结果。这些天线在 VHF 频段的各个黑白电视频道和彩色电视频道上都能保持良好的定向特性,它们的结构和增益各有不同,可供电视讯号强弱不同的地区作金频道电视接收使用。
This article describes several types of VHF all-channel TV antenna receiving the principle, structure and test of some of the electrical characteristics and calculation results. These antennas maintain good directivity on all black-and-white television channels and color television channels in the VHF band. Their structure and gain are different and can be used for the reception of gold channel television in different areas of the television signal.
