同轴通信电缆.第4部分:辐射电缆分规范

[中文适用范围]： IEC 61196的本部分适用于辐射同轴通信电缆。这些电缆旨在用于无线通信系统，例如隧道、铁路、高速公路、地铁、电梯以及传统天线传输不能令人满意甚至不可能的其他装置。应结合 IEC 61196-1:2005 一起阅读。 [外文原描述]： IEC 61196-4:2015(E) applies to radiating coaxial communication cables. These cables are intended for use in wireless communication systems, such as tunnels, railways, highways, subways, elevators and other installations in which conventional antenna transmission is not satisfactory or even impossible. This third edition cancels and replaces the second edition published in 2004. This edition constitutes a technical revision. The main changes with respect to the previous edition are as follows: - a definition for coupling loss was added, - Clause 4 "Materials and cable construction" was added, - rated temperature range, operating frequency and radiating characteristics as standard rating and characteristics were added, - identification, marking and labeling was added, - the tables of test procedures were revised, - quality assessment and packaging was added, - Annex C, "Coupling loss around circumferential orientation of radiating cable" was added, - Annex D "Radiating intensity around circumferential orientation of radiating cable" was added. This publication is to be read in conjunction with IEC 61196-1:2005 .
