This article focuses on antennas, cables, splitters, and related components in wireless microphone systems. It explains how antenna length, type, and impedance relate to wavelength and signal transmission, and provides guidance for antenna placement indoors and outdoors. Antenna types described include quarter-wave, half-wave (dipole and folded dipole), Yagi, and directional models such as shark fin and Pflaunder antennas.
The article addresses impedance matching, the use of coils for tuning, and how incorrect mounting or touching the antenna can result in signal loss or interference. It explains the use of passive and active splitters, the role of linearity in active devices, and how antenna boosters should be used only to compensate for cable loss.
RF over fiber (RFoF) is presented as a solution for distributing signals over long distances, using CWDM and DWDM technologies. Common noise sources are also listed, including poor transmitter gain, long antenna cables near lighting equipment, and nearby LED fixtures or screens. Techniques like grounding or shielding cables are suggested to reduce interference.
