Abstract: The antenna allocation system is the end of the transmitter and an indispensable part of the medium wave transmission station. It plays a role in impedance matching, lightning protection, and filtering out other frequency signals. Exquisite antenna, feeder, and antenna design can significantly reduce energy loss during signal transmission, reduce interference from other frequency signals, and achieve high-quality transmission. This article analyzes the design of the sky adjustment system for medium wave transmission stations and shares it with everyone.
Keywords: tiandiao system; design; high quality transmission
