The Military electronic metrology station also know as the electronic metrology station The benefits of a subscription: Leaky coaxial cable is also called radiation coaxial cable, which is a type of coaxial communications cable having incompletely closed outer conductor, and it is widely used in the tunnels of railways and highways, subways, elevators as the communications media.
Ied cables are intended for use in wireless communication system, such as tunnels, railways, highways, subways, elevators and other installations in which conventional radio transmission is not satisfactory or even impossible.
The main changes with respect to the previous edition are as follows: Detail specifications, based on the blank detail specification, may be prepared by a national organization a manufacturer, or a user.
This edition constitutes a technical revision. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.
