COAXIAL COMMUNICATION CABLES –

Part 4: Sectional specification for radiating cables

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 61196-4 has been prepared by subcommittee 46A: Coaxial cables, of IEC technical
committee 46: Cables, wires, waveguides, RF connectors, RF and microwave passive
components and accessories. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 2015. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) rewrote "1 Scope" to be consistent with other blank detail specifications of coaxial cables;
b) updated different standards in "Clause 2 Normative references";
c) added the definitions of uniformly radiating type cable, stop frequency band and link loss;
d) added different materials and constructions in 4.2 to 4.5;
e) added "Clause 5 IEC type designation";

f) added a detailed rated temperature range of different materials in "6.2 Rated temperature
range";
g) added detailed frequencies in "6.3 Operating frequency range";
h) added "6.4 Stop frequency band" and "6.5 Radiating characteristics";
i) added different detail requirements or typical values in 8.2.4, 8.2.7, 8.2.8, 8.4.3 to 8.4.8;
j) deleted "7.4.4 Ovality of outer conductor";
k) added "8.2.11 Link loss", "8.4.9 Adhesion of dielectric", "8.4.10 Shrinkage for insulations",
"8.4.11 Maximum pulling force of cable";
l) used IEC 61196-1-123 and IEC 61196-1-124 in the electrical requirements to replace
Annex A and Annex B respectively and deleted Annex A and Annex B;
m) added "Figure A.1 Example of testing coupling loss around circumferential orientation of
radiating cable (Y-Z)" in Annex A.
The text of this International Standard is based on the following documents:

so that part of the electromagnetic wave energy transmitted or received through the cable is
coupled by a bidirectional transmission system formed by the outer conductor of the cable and
the external environment

Annex A
(informative)
The coupling loss around circumferential orientation of radiating cable
A.1 General
If required, the radiation characteristics of radiating cable around the circumferential
orientation (Y-Z) can be evaluated in addition to the coupling loss. Annex A gives a method
for evaluating radiating characteristics by the coupling loss around circumferential orientation
of radiating cables.
