多部发射机共用一副天线已应用于中波和调频广播。在分米波电视广播中,由于波长短、天线相对带宽很宽,所以分米波电视广播天线经常运用多工器。在米波电视广播中图象和伴音几乎都经双工器共用一副天线。然而电视发射机与多部调频发射机共用天线的还不很多。本文介绍我局自行设计制作的 Multiple transmitters sharing a single antenna have been used in medium wave and FM radio. In the decimeter TV broadcast, because of the short wavelength, the relative bandwidth of the antenna is very wide, the decimeter TV broadcast antenna often uses a multiplexer. Almost all of the images and sounds in the Mibo TV broadcast share the same antenna via the duplexer. However, there are not many television transmitters sharing antennas with multiple FM transmitters. This article describes our own design and production
